Goodwin Racing NC MX5 Wheel Guide

[@davea1317]

Thanks for the NC support guys, it is genuinely appreciated! Cannot wait to get back to racing this thing with the new wheel setup!!!!

[@manny.camera]

Does anyone love NCs more than Good-Win-Racing?

[@joebauers8062]

I don't know but I am happy to see someone who appreciates them and supports the aftermarket community. GWR is a great group for both their commerce and their informational support! Thanks to @Good-Win Racing!

[@EmmaHopman]

I think it's a tie

[@RLVGReviews]

Exactly the video I was looking for, just got an NC!

[@tennisthehilife]

Perfect timing, I'm in the market for suspension and wheels for my new to me NC 😊

[@alexcable4988]

I have never seen such a good well laid out guide to which offset wheels would fit on a car super helpful

[@dielaughing73]

This is the most useful video I've ever seen for fitment options on the NC. Saved for a later time when i have some money...

Awesome vid. Now we just need a Good-Win ND1/2 wheel guide!

[@weakie87]

Thanks a ton for this. Super helpful!

Great folks to deal with.

[@dustyy_d]

I’m “that guy” lol I’m on 17x9 +25 with -5 camber and rub with rolled fenders. I want to start getting in to track and have a nice alignment to fit that. I’ll probably need a less aggressive wheel to fit that but I also want a nice fitment for the streets. Also if I raise the car it would help lol. Thanks for the info on the specs helps a lot.

[@pashag.1577]

what did you end up doing? i inherited 17x9 +25 and wonder if i should be trying to "make it work"?

I’m looking at buying 17x9 with an offset of 30. They have 255 tyres on. I’m wondering what size tyres are you running with the 25 offset?

[@1968lr]

Excellent video

[@wymotome]

I've had a heck of a time finding wheels that actually clear the accessory MazdaSpeed big brake kit on my NC. PF-01 in a 17x8 ultimately does it, but I've never been in love with the looks of it. Would love to discuss with someone what options I have in the 17" wheel size that will allow caliper clearance and that I don't have to roll the fenders if I run a 235 tire on it. I do appreciate the time you guys took with the video here, especially on the older NC cars.

[@GWRTeam]

Have a look at our Konig Hypergram in 17x8, 17x9, 17x10, made to clear big brakes. We would need template of that MazdaSpeed kit to check for you but likely it works. www.good-win-racing.com/Mazda-Performance-Part/61-1901.html

[@DriveBreakFixRepeat]

How far inboard can we go though without contacting the suspension? A lot more options if you look at S2000-spec wheels, like 17x10 +50 or similar.

[@toshibavoodoo]

I'm the proud owner of the 2012 NC PRHT, and LOVE IT! I'm running 225/45R17, and want to move to a 225/50R17. Can I do that? Fender Roll? Higher suspension? THANKS!!

[@GoodwinRacing1]

See our notes on tire diameter at 7:00 in the video. A 225/50/17 is almost 26" tall. On stock suspension you might be OK but that's too tall for a lowered NC unless you limit your suspension travel by half an inch or so by adding spacers to your bumpstop so you bottom out the suspension sooner (before the tire hits the top of the wheel well), but that means you'll be riding on the bumpstops very often. We wouldn't recommend it. The 25/45/17 is a much better fit for the NC.

[@toshibavoodoo]

Thanks. It is lowered, so will keep the 225/45s. Great videos.

[@dungernator]

I'm looking to run a 225/45R17 on a 17x8.5 +40 I'm guessing I'll need to roll my fenders? My cars lowered with around -1.5 degrees of camber. Any help would be appreciated, cheers

[@GWRTeam]

Yes, we think you will need a mild roll

[@ferrarienzo5252]

Would a 17x9 +35 work with some negative camber and fender roll?

[@michaelmartin4111]

Love all the knowledge you guys are sharing! Any comments on when an 18" wheel would be a good option for an NC?

[@GoodwinRacing1]

Thanks Michael. We covered just 17" wheel sizes here because 17" is better than 18" in just about every way. 18's are heavier and thus hurt ride quality and performance. The one situation where we do sometimes run 18's is when for a certain competition class the tire model or size we need to run is not available in 17". Otherwise, we recommend 17".

[@michaelmartin4111]

@@GoodwinRacing1 Gotcha! I have some 17x9 +45 RPF1 on mine right now, but the tires are some 215s from the pervious owner. Would love to go up to a 235 to put some more tire to the ground. Right now the only other modification are some Fortune 500 coilovers. Would you recommend upgrading sway bars and links first, or do you think I would I see more grip/stability from the tire upgrade before sways? It's mostly a street/canyon carver.

[@GoodwinRacing1]

@@michaelmartin4111 Love those RPF1s! You're just a fender roll away from being able to run 235 or 245 tires on those wheels. Ultimately, you'll probably want to add sway bars with the added grip, but there's no right or wrong answer on which order you do it in. Which sway bars will be right for you depends on how sticky of a tire you go with. Check out our RoadsterSport sways if you're sticking to a standard street tire, or Progress sways if you're doing a sticky summer high performance tire.

[@lassydogpie5390]

What’s best size to look flush without spaces?

[@RobWhittlestone]

What about 18x7.5 or 18x8? My stock NC2 wheels are 17x7 I'd like to go to 18 inch. Street use only. Currently stock Bilstein suspension, no aftermarket coilovers.

[@andrewfernandez3827]

Hopefully you take the time to reply to this! I found the perfect set of wheels when it comes to style and price in 17x9 +45mm offset. Is that extra 3mm going to give me issues w/ rubbing if I don’t lower the ride height too much? I’ll fender roll if I have to lol

[@lukasrydelius6174]

I have stock 17x7 on my 08 gt. It has 225/45 on it Why would anyone go up to a 17x8 just to have the same width tire? What changes when you have a wider wheel with the same width tire?

[@burgholte]

Do you think a 245/40/17 with a 17x9,5 +45 wheel will fit without rubbing? Fenders rolled aggressively ofc, it just shouldn’t rub

[@businessmanph]

On my 2018 I have been on 205 front and 225/45-17 on rear stock bbs 7 in wheels. How would the car differ in steering with 8 vs 9 in?

[@joneshank1]

[@markobermudez8765]

will the 17x8 45 offset RPF1 clear front wilwood brake caliper?

[@AlexM-np1cx]

No.

[@pashag.1577]

how do i stuff a 17x9 +25 under the fender? is that even possible?

[@trevorhsu-mdh-5684]

Aren't the NC 16" wheels 16x6.5, not 16x7? I ask because I want to fit 225x45 R16 tires on the stock 16" wheels but the specs for the tires say the minimum wheel width is 7" so my understanding was that these wouldn't fit.

[@GoodwinRacing1]

Yes there is a 16x6.5" factory wheel. A 225/45/16 will fit that (many popular tire fitments deviate from manufacturer's "recommended" wheel size) but that's going to be very wide for a 6.5" wheel. Would work on the street but we wouldn't do competitive driving on that combo.

[@Balance2097]

Is it possible to run with a 17x8 ET54?

[@jessepinkman01]

What about 16" wheels?

[@productdesign9626]

What is the verdict on Rota wheels? They are made in my hometown so they are by far the best value I have seen for a known brand name. I'm not sure they are particularly light though.

[@GoodwinRacing1]

Indeed, weight is the concern with those. We don't carry them because every model we've looked at has been substantially heavier than the options we do carry.

[@productdesign9626]

@@GoodwinRacing1 thanks, I feared as much

[@absoluteclownworld]

I currently have on my 2014 NC ( on stock suspension ) 17x7.5 +35 with 215/45 tires ( indy 500s ) and I'm currently tramlining and having a bump steer effect going on.. alignment is -1.4 camber all around and caster is around +5. Any advice?

[@briangoodwin2862]

For the tramline you can usually dial that out with some alignment toe in all around. We like toe zero and even toe out for autocross but tramline is increased, go toe in with same numbers all around to cut that down and that's what we typically suggest for non racing street users. On the bumpsteer, wheel offset is likely the issue, scrub radius error is just a bit much when you push way out to 35mm. You could easily run same tire size at 40mm or 45mm offset and each step inwards would mean less scrub radius error and less bumpsteer.

[@absoluteclownworld]

@@briangoodwin2862 Okay thank you I will add a little toe in front and back. Also I will have to save up for some different wheels then, guess I'll go 17x8 +40/+45, using same tires. Thanks.

[@samuelschelling5382]

What is your opinion on Staggered setup like 17x8 215/45 front and 17x9 235/40 rear?

[@briangoodwin2862]

We much prefer a 'square' setup, or same size all four corners, for a car like the Miata that has a 50/50 weight balance. Easy to run 235/40 all four corners, then you have a balanced setup, can still rotate tires, etc. You can use 235/40 on 17x8 for street, or 17x9 for track. See NC wheel intro page and 'max size' tab for a lot more detail. www.good-win-racing.com/Mazda-Performance-Parts/MX5/Wheels-Tires.html

[@demon1954]

What's better on road or track? 17x7 OEMs or 16x8 RX8s?

[@GoodwinRacing1]

On the race track, wider is "better" (faster). But one thing to be wary of with 16" wheels; tire selection is far more limited than 17"!

[@demon1954]

@@GoodwinRacing1 Ah! Good thought. Thanks for letting me know. Does it also follow that there's yet more tyre choice with an 18x8? Or does that involve more lowering, camber, and rolling?

[@GoodwinRacing1]

@@demon1954 17" has the widest variety of tire options in sizes that work well on the NC. 18" tire selection is better than 16" though. We never run 18" wheels on the NC because the 17" is lighter... the only exception is on some of the pure race cars when we want super wide rubber and they don't make 17" wheels wide enough, so we have to move up to 18" for an 18x10.5 or 18x11. But for 10" wide and below, there are plenty of great 17" options and those will ride and perform better than the heavier 18".

[@demon1954]

@@GoodwinRacing1 Thank you.

[@sutton3199]

This is probably something to ask more about on the forums, but do you keep the plastic fender protector things in the fronts when you do a fender roll? Or do you just get rid of them entirely? I've personally never done a fender roll and always wondered about that having owned a 2010 NC for 8 years now

[@GWRTeam]

Fender liners stay, remove any retaining hardware between fender and liner and then pinch the edges of the plastic in the rolled up fender lip.

[@sutton3199]

@@GWRTeam Okay cool. Thanks for the response!

[@thinmint6778]

With 17x8 +35 would i have to roll all 4 fenders?

[@GWRTeam]

Depends on height, camber, and tire choice. Tires larger than stock size, such as 215mm or wider may required a fender lip roll.

[@trigz1689]

Hi any idea if a 225/45/17 will fit on a 17x8+44et? Cheers

[@GWRTeam]

Yes, that tire will fit the 17x8 rim. With that tire/wheel combo you will need -1.2 degrees or more of camber to clear the factory fenders.

[@trigz1689]

@@GWRTeam awesome thanks. And no fender roll should be required with that amount of camber?

[@trigz1689]

The car will also be slightly lowered

[@lakessbm]

How to measure if the wheel will tuck flush behind a rolled fender?

[@briangoodwin2862]

You either know what you are looking at from experience, or you can pull spring and jack spindle up to watch what happens at full suspension compression. See wheel product descriptions on our site, with most of the wheels we know what it will take to clear and we tell you in the product descriptions and at front of wheel sections by generation of Miata.

[@lakessbm]

@@briangoodwin2862 thanks. I'm not just looking to clear tho, I want a super flush fitment

If you want to avoid fender roll we suggest max of 225/45.
