My wheel setup and what tires size
 

Ok I got rid of my 19's for some 18 RPF1 18x9.5 +15 and 18x10.5 +15. I saw Megan running this same setup up front with no issues on AP BBK. He told me he had 3mm clearance. Well after I installed the out side lower edge corner only of my AP caliber was ever so slightly rubbing the inside of the wheel where it angles inward. This is how close it was, the wheels had been plasti dipped and the plati dip was rub clean but no marks what so ever on the wheels. It looks as if the caliper had a slight molding issue for it wasn't round and smooth as the upper corner. Again Megan had clearance. It actually has a small hook like look. I almost thought of grinding down a tad. But t thought of that on my AP's is hard to manage.

So I'm going to run these wheels and spacers are going to be needed to ease the mind and as my buddy Mike mentioned you want some clearance for small rocks can get caught between the caliber and the rim making awful noise which has lead him to black flags before. I was thinking of 2.5mm spacers but my buddy had some 5mm he gave me. So that's what's on there and that's how it's going to be so no grief just help on tire sizes please.

I want to run a square tire setup of 285/35/18. Shouldn't his work up front? I really like to get a 285/40 but that tire size seems hard to come by with the few brands I will only run. I have coilovers so adjusting height is no issue. I ask cause the great info here is spread far and wide with different scenarios. But now with my total offset at +10 I had to ask. I will be running -3.0 camber also.

ive tested 18x10.5 et23 with 275/35/18 up front at -3 camber with no rubbing. 10.5 at et23 is the same outside clearance as 9.5 et10. thing is 285/35/18 is a wider and taller tire then the 275/35/18 i was running. But on a side note i feel 285 is too wide for 9.5, leading to crappy sidewall dynamics and not maximizing the actual width of the 285. i wouldnt run 285 on anything less then a 10, ideally on 10.5 which is what im running now. Also, when i do run 275/35/18 ( my Maxxis RC1 since thats the biggest size they make right now) i spacer out my rear 10.5 et15 to et5, -2 camber back there also no rubbing

Subbed...I just got the exact same wheel setup :)

Well I orders some RS3 's 285/35. I'm sure it will be fine. Going to run -3 or more camber up front. The manufacture recommends a 9.5 wheel and up for 285.

your tires shipped, they will be at my shop on Wednesday.

I'll be there Friday with wheels and $.

the range for the 285/35/18 RS3 is 9.5-11, so the 9.5 is at the bottom of the range, and i know for a fact, even ask Martin, the "285" Rs3s are over 290mm, they are prolly the widest "285" street tire around, Hence why i recommended 10.5 which i run myself.

My setup is RPF1 , 10.5 x 18" square with the rs3 285. No rubbing at all, but I do not have camber settings either. Will be interesting to see what happens with drop+ camber.

I'm sure I'll be good. Tires are here. Picking them up tomorrow. But my wheels will be waiting to get powder coated.

My 285's are a little poochy on my 10" rears, I think on a 9.5 they'd be ridic, but it probably depends hugely on the tire.

LMK what you think of those RS3's. I can't wait to get rid of these 19's and get RPF1's.

It won't be nothing. I was already running a 275 and it was flush with the wheel so this will be about 1/4" more on both sides.

I went with Enkei PF01 18x10.5 +38 front +15 rear. I test fit the +38 front recently over the sport brakes and it seemed like it fit fine without the 10mm spacer I originally ran them on but I will have to put them on a drive a bit to see for sure. For tires I have Toyo R888 275/40-r18. As you said, the 40's are hard to find. I wanted NT01's or RE-11's but they just were hard to get ahold of. Unfortunately I have my car lowered and can't get up my driveway with the slight additional drop the 35's would give me. I also don't feel like lugging my rims/tires to the track to put em on there.

I hear ya man, getting really damn sick of swapping wheels lol.

Everyone going square, hmmm...

I wanted to run the bfgoodrich Gforce rival since tire rack has it beating the re11 in every dry test. Seems I have to be 275/35 or 295/35 to be square or maybe stay staggered with those numbers. They seem light too. The re11 only has a comparable size in the 275/35 but its 2 pounds heavier :).

I can tell your turbos are not installed yet since you want to go square on the tires!
