Tire +/- size guide for FR-S/BRZ

I believe that interview was poorly translated and/or out of context. Technically 235/40/17 will fit and offer better clearance than stock if mounted on 17x8 or 17x9 +35 wheels; 245/40/17 will be about 2 mm closer to the suspension than stock. I think the engineer was referring to retaining the "fun to drive" feel, which is subjective. "Fun to drive" for the Toyota engineers is hanging the ass end out around a corner; my opinion of "fun to drive" is maximum grip/maximum g's/low lap times.

but yea, only really one tire size. thats why im kicking the idea around. the 235/40-245/40 is really looking like a nice bet. 17x9 all around with a 235/40 should be a killer setup on this car

I thought people said it takes 16s to clear WRX brakes. I could be wrong as I wouldn't own one of those pigs :P

17x9s are hard to find in decent light and < $350/wheel options in 5x100 from what I remember when I spent 30 minutes or so looking before. Have you found any that fit that aren't 500-800 per wheel that aren't > 18lbs each? Let me know which ones if you have so I can consider them I was thinking I'd have to go with 17x8s (8.5 is the spec wheel width for star specs in 235/40 and 245/40 IIRC), so was leaning towards the RPF1 or PF01 in 17x8 +35.

Call up Enkei USA, you'll find they are happy to drill out a 17" x 9" wheel at 5x100 instead of the usual 5x114.3.

My buddy emailed them about doing it, and I think he was quoted <$300 per wheel!

Nice. See normally I'd be too lazy to investigate that enough, but now that I know

Or you can just order them from my friends at Dezod Motorsports.

Remember, those pigs have their roots in rally and the 4 pot WRX caliper with the same rotor size as BRZ was made to fit a number of 15 inch rally wheels. There are a few other lighter options that work too though that's not really my area.

The 4 pot WRX caliper may have better clearance than the BRZ sliding caliper but I do not know.

We will find out soon enough

Better to listen the engineers who built the car, rather than the ones who just signed the cheques.

I've owned enough to start a bacon factory. Numerous rally wheels will fit over those 4 pots (Speedlines, TDs, etc). They might not be the weight you are looking for, but you sure as hell won't break them.

Ive been waiting for a guide like this. Is this a legitimate source? the amount of hooplaw has me worried.

[SkullWorks]

I already pre ordered rs-3's in 255/17 (40 or 45 section width, cant recall atm)

so...turns out that's gonna fit...im sure...., I'mma wait til I get the car to order my rims everyone is going to hate on my car so hard I can't wait to piss everyone off with my rim choice...hint it's functional,

I remember the review - it was one of the "first drives" over in Europe.

I read the quote more about ruining steering feel as opposed to physically fitting. Same problem the new Mustang engineers had - they wanted even skinnier tires on the front but figured the general public would think it was a joke. I suspect the 215s are part of the "near 911" steering feel we read in reviews.

Big assumption there about the guy being interviewed. And I'd love to "listen to the engineers that built the car" but I have never heard one talk about what wheel sizes fit other than him. Link?
