Lexus IS300 Brembo 17z 6-Piston Porsche Audi Brake Calipers

[@Ig2gpce]

I'm so stoked to be doing this to my own car soon, just gotta track down the front calipers at this point. The guy at Overkill Engineering was amazing to deal with! Such a chill guy

[@TunerwithKids]

I would really recommend getting a 5” disk for the inside clearancing for rotor. That 4-1/2 new one I used was good then it got too worn. The backside clearancing for the steering knuckle can be done with a cutoff wheel. I picked up that HarborFreight electric cutoff tool after I already did the knuckle on back side. amzn.to/3hyOxoJ

Man you went through THE STRUGGLE for all of us. All the extra tips are very much appreciated. Very very good videos dude.

[@usa5046]

Very nice I'm working on my set right now

[@LexusRepair]

Professional work Good luck bro 👍🏽

[@UnapologeticIslam]

I would go with overkill engineering for the rear retrofit as I don’t know of any other cost effective BBK setups, but the front isn’t worth it in my opinion.

[@FamiliaColl]

For a 2015 IS250 F-sport would this work and if so what would I need in.order for them to work. If not I'm planning to ipgrade to the IS350 calipers and rotors.

[@tahasultan7409]

Hey quick question, for the rear caliper swap on the IS300, can I use the factory bolts to bolt the Porsche Cayenne calipers on the car?

[@syndicateautoworks866]

Hello I just saw you're channel great documentary on your build! I registered for the overkill engineering page but I'm having trouble finding the kit for the BBK kit how can I order those brackets?

[@TunerwithKids]

You need to DM him on IG. He will respond there.

[@syndicateautoworks866]

@@TunerwithKids great thank you what's his IG?

[@Soltor1974]

What wheels are you running? I did a bremdo swap on my is300 the hardest part was finding wheels that didn’t need spacers but glad I did it

[@TunerwithKids]

I have my SSR Koenig but need spacers. You will need 18 or 19 with high disk to clear.

[@Soltor1974]

@@TunerwithKids I went with 18in 5 zigen Fnor1-c didn’t need spacers but it’s a super tight fit

[@TunerwithKids]

Yea, Brembo is pretty good about trimming enough to clear wheels. The front 17z are giant. My rear SSR also need a 2mm space to clear the 17z rear calipers. I’m tempted to machine the face of caliper down to avoid it.

[@Soltor1974]

@@TunerwithKids yea they are giant that’s why I asked about the wheels. But it looks cools so well worth the struggles

[@Soltor1974]

@@TunerwithKids be careful one day on the 405 I got a rock stuck between my caliper and my wheel messed up the wheel alittle but I was pissed 😤 sounded a lot worse at 80+mph I was shook figured the wheel was coming off

[@CH121S]

How much are those brackets? Googled it couldn't the price.

[@TunerwithKids]

They are $150 front and $150 for rear. Check out @overkill_engineering on IG. DM him.

Earned a sub from me ! Great content man

[@ricardohumber3756]

Would the 18z calipers work on the 2nd Gen GS300?

[@TunerwithKids]

17z may work with Supra//SC brackets. Contact Overkill Engineering IG to see if he has brackets.

[@MrDestrozalmas]

Where can I buy Brembo brake adapters?

[@TunerwithKids]

Overkill engineering on IG.

[@javaughnpryce360]

Can I have the link to that adapter bro.. the first gen is300 basically has the same suspension and brake setup right so I can use the same adapter

@@TunerwithKids Thanks Binh! Should've looked back at the previous vids channel haha. I'm really a fan the work you put into the cars, very quality content!

[@TunerwithKids]

I got lots of vids so it’s hard to go thru them all.

[@thecookeman]

any idea what size wheels on the front you can run without spacers? i have bought the 350phi kit and trying to get 8.5~9 wheel on the front

[@TunerwithKids]

It depends on spike design and hub spacing. You need a high disk hub to clear most BBK.

[@thecookeman]

@@TunerwithKids just to add. Great channel with some awesome DIY ideas. All the way from Australia thanks again for your help and guides!

[@andruhanovo6583]

What is the distance between the mounting ear bolts? (Center to center)

[@christiandrakes4566]

Is there any other company that makes the brackets? Overkill engineering seems to be down

[@TunerwithKids]

He only one who makes it. He just ordered a new batch and is on vacation. It’s been back ordered for 2 months. Give him a few weeks.

[@ttran8538]

The brackets look thin for aluminum, is it special grade? Can you share the thickness? Thanks

[@TunerwithKids]

They are steel.

[@JDG.7R]

im looking into getting this done but my interest is what size wheel will clear it. 18s of course but like more so offset & width to clear the calipers front & rear, what did you go with?

[@TunerwithKids]

I have 3-piece SSR with low disk and neither clear. You need high front disk and medium rear to clear. On 5th Gen Celica forum, the owner, Overkill Engineering has good info and has the caliper to disk measurement. Gotta register for forum to view.

[@JDG.7R]

@@TunerwithKids ok gotcha lol bbk problems might have to run some spacers

[@odusseasaggelikas4389]

I want to put 330mm to 17z's for 17wheels could I;

[@TunerwithKids]

Not on the IS300. The location of the stock mount ears and the steering knuckle won’t allow enough room to create a bracket they will line up or have full pad contact.

[@odusseasaggelikas4389]

What can I do to put 17z 6pot on 17wheels

[@odusseasaggelikas4389]

Mazda 323f v6 ba

[@TunerwithKids]

There are probably a few (very few) 17 inch one piece with concave face that might clear but it’s a long shot. The caliper is massive height and face clearance.

[@odusseasaggelikas4389]

If it goes with a disc of 330mm it seems that 17z's is for clearing 17wheels

[@reynaldomunoz6538]

Can the stock brake line be used for these calipers ,?

[@TunerwithKids]

Yes using stock banjo nuts. But probably want to invest in some stoptech stainless lines. They are $100 for set.

[@tigwelding123]

is there bracket for rear tt supra to is300????

[@TunerwithKids]

Check overkill IG, he’s been making Supra and SC300 stuff too.

@@TunerwithKids guess that’s the next wheel setup lol I’m doing the brakes right now

[@TunerwithKids]

You found some GS-F wheels for cheap?

[@UnapologeticIslam]

Great video but honestly this is way too much work... The IS350 calipers and rotors do a much better retrofit and all you need are two adapters available on eBay. No trimming or shaving required. I have them on my IS300 and they stop like a dream.

[@TunerwithKids]

Yea much more work than expected. Would have gone with ISF 6-pot for $300/each new and 350phi brackets for bolt on. But this was more for the challenge and experimentation.

[@joelbenitez5794]

does this only work on newer is300

[@TunerwithKids]

The brackets that Overkill makes is for the IS first Gen. he did make some GS brackets recently.

[@R.O.A.P.]

Does anyone know if he still makes these?

[@TunerwithKids]

Check with overkill Engineering on IG. He makes these in lots.

[@pksystems4714]

Those calipers are way too small for the rotors. 18Z caliper is prob What you should have used.

[@TunerwithKids]

There isn’t any clearance for 18z on is300 or contact surface of the rotor. Overkill_engineering is pretty experienced with this and he got it spot on for pad contact and clearance.

[@justintowers8230]

why the hell you guys call it spindle. is that some sort of German term? toyota part number is called knuckle. I dont like these calipers, they are not radial mounted like the LS430 calipers

[@TunerwithKids]

Spindle spindle, knuckle, hub assembly. All same shit. In an automobile, the wheel spindle, sometimes called simply the spindle, is the part of the suspension system that carries the hub for the wheel and attaches to the upper and lower control arms.

[@Rikverse24]

What rotors in mm Diameter do you use? And why shave Z17 and not just use Z18?

[@TunerwithKids]

18z is too big.
