GT4 Camber Plates and Toe Links from Tarett

[@TRZ0612]

If I had to do my suspension mods over again, I would have opted for camber plates instead of bottom shims. With the shims I needed the caster pucks to correct caster and a bump steer kit because the shims did change the geometry and the steering wheel was too jerky without it. So far I have the MCS 2-way remote dampers, caster pucks, rear toe links, bump steer kit and going in next week are the rear end links.

Killer vid as always Danial. Damn your car looks good, especially with these Apex wheels!

[@JetFuelOnly]

Thank you!

[@edub0]

Thanks!

[@JetFuelOnly]

You’re awesome! Appreciate it!

[@jecheverry4]

Great video. This May solve my issue…3rd time going to tuner to try to get this right. I have all the same parts as you…do you know how many mm were used for shims in combo w the camber plate? I believe stock already has about 7mm in the LCA. Did you add more or left the oem shims and adjusted camber via the plates?

[@JetFuelOnly]

I am back to stock shims in the front which I believe you are right - 7mm

[@JetFuelOnly]

So it’s too plates almost all the way in and stock shims.

[@henr1k5]

Thanks! Going to replace my stock camber plates with GT3 Cup camber plates and was wondering how to do it... Seems easy!

[@angrydwarf6563]

Great content. Love these vids. Really informative. Nice one.

[@JetFuelOnly]

Thanks!

[@scottoconnor3484]

I’ve got - Front bump steer tie rods, adjustable caster pucks, caster plates, rear toe links, Monoboll control arm ends, Tarett Locking Plate Kit for Rear Toe Links, Tarett/Wevo Semi Solid Transmission Mounts. All are working great together. On Apex 19” wheels, 275’s in front and 305’s in the rear. No rubbing.

[@JetFuelOnly]

Solid trans mount? Did it make things a bit noisier or harsh?

[@scottoconnor3484]

@@JetFuelOnly yes and no. On my first drive after all the work was done, the most noticeable element by far was the very visceral sound and feel from the tranny mounts. But, within a few drives, that was just part of the package and became less noticeable. On the track everything is firm and predictable.

What spec wheels and what brand/model tires?

I know spacers add to the Ackerman effect but will 11mm spacers be an extra issue?

[@JetFuelOnly]

Hmm not sure. It’s already prevalent with the alignment I have but I have 15mm spacers on another car with no noticeable issues.

[@981_pdk]

Nice video and great wheels. I am running Apex wheels on my base 981 Cayman. I have rear toe control and front lca’s from Elephant Racing with X73 suspension. Likewise -2.5 Neg camber. I originally fitted plus one size MPSS 275/40/18 but now use Trofeo R Cayman Cup tyres in 265 which are wider then 275 Michelins! they are awesome can street drive in wet no probs and they don’t wear out like Michelins. At 32degrees hot temps grip is amazing. Another good thing about Trofeos is there is no choppiness in the ride and everything is about moving forward. My car has no trouble taking on more modern Porsches especially in the corners.

[@JetFuelOnly]

Interesting. I’ll take a look at them!

[@peterbrown3045]

How did you fit 305 rear tires? Camber plates needed up front for the 265s but it does not appear you have rear camber plates. The Apex site now states you need both front and rear camber plates for the 265/305 combination. Really enjoy your channel since acquiring my 2020 GT4 this summer.

[@JetFuelOnly]

The video shows the plates being installed up front. Did you see? Rear camber can be accomplished with the rear toe arms. I have 2.6 back there. The toe arms aren’t for the camber though, stock parts will result in toe out of spec when you put that camber in the rear, the toe arms allow it to be in spec while getting extra camber. I see what you mean on Apex fitment guide. Again they didn’t do their fitment research well enough from the beginning since it’s been revised at least twice. Rear camber plays are another way to do it though and will get you a bit more.

[@peterbrown3045]

@@JetFuelOnly I did see the Camber plates up front and I understand that aftermarket adjustable toe arms are required to dial back the correct toe when adding camber in the back. I didn't know that you could get -2.6 in the back without aftermarket camber plates. Just confirming it looks like you did. Cheers.

[@JetFuelOnly]

@ got ya. Yeah not sure why Apex says rear camber plates now. It can be done without

[@peterbrown3045]

Last question. How did you achieve -2.6 in the back? Did you have to use shims and if so how many?

[@JetFuelOnly]

@peterbrown3045 I think shims were removed to keep it from rubbing the fender. I can’t confirm if any are in right now as the car is at the dealer

[@confirmhandle]

😊 thank you For this content! Great job sorting it all out. I just picked up a GT4 718 and I got 19" apex like yours, I want to do 295 & 245. Do you think I should go with these tires I drive pretty hard on the track but I do have to drive it home. Just burned out and delaminated PS4 at local track with alotnof right hand turns

[@JetFuelOnly]

I would say don’t go with the RT660s. My second set started to delaminate. Turns out this happened to some people. The separation happens where the plies are bonded together ACROSS the tire. I’m currently on Nankang CR-S. So far so good. I would try to do 255 up front at least. 985-296 in year is fine.

[@jamietonksracing7367]

Great video, thank you for doing it Can I ask on the final alignment spec to get 3deg and 2.4 were the shims that of standard? I’m aiming for something similar so I sure if I need to buy shims. I’ve got the same top mounts, toe links and locking kit on order

[@JetFuelOnly]

I believe the stock shims are still in there. If you don’t use camber plates you will definitely need a shim set.

[@victorjialangli1976]

Awesome video quality and editing!!! Just found your youtube channel via Erika. :)

[@JetFuelOnly]

Thanks for watching!

[@danildrozdov9899]

Thans for great vid and info! Deciding between MR OEM Kit or this two Tarett parts, just have a little concern regarding a strut tower failure... Can tarett/MR top hats lead me into this problem? Or am I worrying too much?

[@JetFuelOnly]

I haven’t compared the MR against it. But I’m not sure anything is going to help with the tower failures or make it worse. Porsche might be likely to warranty the situation with MR parts over Tarrett. But no one knows if that will be the case.

[@KurokoShirai]

Melody has worked on my honda in the past! Great shop. If I want to run a sporty/mild street setup on my 718GT4 like -1.8/-1.8 and 9/10.5 from apex, do you think I need anything more than just toe links (got TPC from a friend)? I don't think I'd need front plates if I just want to run 245/285 on 9/10.5...

[@JetFuelOnly]

Hmm I would think 245 might fit but at 1.8 it may be close. I wish I felt more confident about the recommendation

[@cpayne6]

Hey man, loving this Cayman content! Just thinking about doing these mods to take it from what I can maximize stock to fit larger wheels and optimize it for the track. How do you feel with an aggressive set up like this on the street? Any issues? Thanks!

[@JetFuelOnly]

Definitely no issues on the street. Except maybe in her shoulder where if you’re not putting the work in at the track. Ha ha.

[@tariqyunus4605]

Have you lowered the car beyond stock?

[@JetFuelOnly]

It was 10mm lower than stock but my shop needed to bring it up a little to make this setup work without rubbing

[@michaellegere4823]

How are you liking the camber plates? Are the noisy at all?

[@JetFuelOnly]

So far great! No extra noises.

[@RudyP18]

Cool video - I think you are in my area (Bay Area) - if so, where do you get alignment done? I want to do similar camber (plates for front, plus shims and toe links for rear) on my GT3 but don't have a shop to do the alignment. Thanks!

[@RudyP18]

Never mind... I was midway through the video when I posted the comment and I see you went to Elite Performance.

[@rka132]

Nice video! Do you have any noise issue, with the toe links? My plan is to install these on my 718 GTS.

[@JetFuelOnly]

No noise at all!

[@rka132]

”Sounds” good

[@jensis]

Nice video! Did you also lower the car?

[@JetFuelOnly]

It was lowered 10 cm but we brought it back up to minimize rubbing.

[@philtechGT3]

why not using the 99.1 camber plates to get more camber ? That's what Manthey Racing did on my GT4

[@JetFuelOnly]

991/981/982(718) are all the same.

[@philtechGT3]

@@JetFuelOnly sorry, I meant 991 GT3 RS camber plates

[@JetFuelOnly]

@@philtechGT3 haven’t looked into those but I suppose that can be done too? The tarett plates give me more than enough camber though and guessing they may be cheaper? Have a link to GT3 RS plates?

You wouldn't have been able to stay in SS anyway with 9" front wheels. I wish I could run 19's, but I'm dumb and spec'd PCCB. I guess I could, but I'd tear up my calipers and they cost WAY too much for that!

Gonna be pricy if you need to change tyres, definitely if it being a track car and changing tyres is a 2 monthly ordeal :p
