Ok well I’m sure this has been answered before but I have read that this will fit w/o rolling and then I read I will have to roll fenders.
here goes:

Rpf1 18x9.5 +38 or (+45) on Conti extreme contact sports 255/35/18 square.

Lowered on Bilstein b-12 pro kit. So about 1.2” at most in the front. Rear maybe 1”?

i don’t really care about being flush per se as much as having enough contact patch for my build (turbo rew engine).

im not opposed to rolling fenders, but trusting a shop to do it without ruining paint is another story.

Maybe go with 9” rim?

I have some Motegi MR145 Traklite V3's in 18x9.5+35 with 245/40 Federal 595RS-RR's. Measuring my ride height from hub center to highest part of fender arch, I am at 13.5" front and 13.75" rear. I have a VERY light fender roll (no pulling at all) to give myself a little extra clearance from the fenders. Zero rubbing or scrubbing even under load while Autocrossing the car. A 255/35 will give you nearly 9mm more wheel well clearance due to the 255/35 being just under 18mm smaller overall diameter, as a result also make you sit a bit lower (nearly 9mm lower measured ground to chassis) so worth keeping that in mind.

Awesome, so maybe a chance I’ll be alright without rolling. I used that calculator and it looks pretty good. I’ll be a little lower so I’ll just watch for driveways and such. So I suppose I can roll the dice and run it. If I have issues I can go from there
Thanks Ricky

I really just want to get the flush look do you think that the wheel will be flush or stick out of the fender and if you have an estimate of how much?

Use the calculator that Ricky put a link up for. It’s not exact but will give you an idea. I would save up for suspension mods first but that’s just me. But no it shouldn’t poke.

Wheels off a genesis 2019+ wondering if they will fit. Im currently going to have a set of these extra (rip my poor g70)
wonder if they will fit the rx8 which is getting engine rebuild

Yes they will fit with plenty of space still left

for 9.5” +38 with 265 tires people in the past had to at least roll the lip protrusion flat in the rear, but some tire widths vary

edit: my memory faded a bit, it was 265 size tires and this has been corrected, but some 255 tires may be just as wide. IMO you should plan for rolling the lip flat.

Went through the 1st 10 pages but lost the will to keep going...so here goes:
Volk Racing TE037 6061 w/ Michelin Pilot Sport 4S
Front: 19x9 +34 255/35R19
Rear: 19x9 +34 255/35R19

Will these fit? I have a feeling it's about borderline from reading others' posts...

Thanks Team. I suppose to go for wider tires this is a small compromise. I’ll update everyone soon as I get them on there. Car still need adaptronic and return fuel system put in. Almost there.

when you absolutely need to make these wheels / tires fit...

Stock r3 suspension and wheels w spacers?
 
Running stock suspension and 245/35 tires on the 19 r3 wheels, i can’t find answers that are 100% for this anywhere, can someone tell me for sure if 30mm spacer rear would fit? 25 in the front? I’m playing with anything from 20-25 front to 20-30 in the back,

so many posts say itll Work then I see the opposite and very few mention 30mm at all? Would it work? Will it fit? Will It rub? Will It rub on corners? What would I have to do?

realky don’t wanna order the 25 and 30mm setup to find Im screwed, thanks!!

not sure if this belongs on this thread I couldn’t find any posts about spacers in it, but I don’t see why not the answers for will it fit I couldn’t find anywhere else,

Hey guys,
I'm on a good deal for some Enkei's in 18x9.5 +27, do you think it will works with 265/35 like AD08R's ? Or maybe 255/35 ? I know i have to roll fenders but do I need too much camber ? It's not my daily but I want to keep it in track specs so not too low and not abusive camber.
Alternative on these Nt03+M is +40, there is nothing in between and they are more expensive...

Hello,

I have a Konig specific question.

I have my eye on Konig Ampliform 18x9.5 +35. Will be running these on 245/40 Pilot Sport 4s.

I can see that Konig offer an A & B variant, with the B variant being more concave and offering less clearance for brake calipers.

I would like to run the B variant on the rear, with the same specs (18x9.5 +35).

Does anyone know if the B variant will cause clearance issues with the rear brake calipers? I can't see the difference in spec anywhere.

Thanks in advance!

Ricky SE3P 03-27-2023 06:15 PM

Ive never had issues with brake clearance on a 9.5+35 setup with a concave fitment on front or rear.

TeamRX8 03-29-2023 11:20 PM

just fender clearance :p

Looking to check fit on these, from what I've read here I feel pretty good about it but wanted to ask before I fuck up.

That should work without any issues....

Mtshaw113 02-18-2024 09:09 PM

Are there any specific clearance issues with an R3? Currently all stock, trying to think about 17s or 18s for track wheels/tires, since 19s are absolutely expensive, dont know if the brakes or something else get in the way or with stock bilsteins. Thanks y'all
