Max and Extreme Performance, 245/40 F&R
245/40's all around, also at your own risk!

The Dunlop Direzza Star Specs are getting rave reviews.
Bridgestone RE11's are likely the highest-performance real street tires you can get right now.
Hankook Ventus RS-2's are very good tires for the money, I have a set on my car. They are great street tires and are also up to track usage. Lower performance than the RE11's and Star Specs, but definitely a more serious performance tire than the S.Drives.
Kumho Ecsta XS are probably higher-performance than the Hankooks, at not much more $$$.

It is worth your time to root around and study the consumer reviews and test results for different tires in the Tire Rack website. It is a FANTASTIC resource!

 

The only reason i was thinking of going 245/45's all around was because wider tire = more grip?

Idk too much about tires but i needed to figure it out soon.

 

That would be 245/40's all around!

You payin' attention?

As far as "wider tires = more grip", it depends.
At the track, in the dry, with tires fully heated up, wider is pretty much better (up to a point).
On the street, tires not fully warmed up, and/or in the rain, wider is not "better".

What are you using the car for? If you're not tracking or autoXing it, I wouldn't worry about "wider", I'd go:
215/45-17 front, 245/40-17 rear (stock AP2 sizes).

If you're SURE you have clearance and won't rub, you *might* consider 235/40-17 fronts, or *possibly* 245/40-17 fronts. But the extra width (and weight) up front can actually conspire to make the car feel more sluggish and less nimble (although ultimate grip levels would be higher).

If you *are* tracking or autoXing it, then you got the wrong wheels. you can run much wider tires with higher offsets, and also you'd want wider wheels to run 255+ width in back, or even all around (8" = 245/40 max recommended width).

 

Zdan, Im deff not tracking or auto xing the car.

What are the size of Ap2 wheels? 17x7?

 

AP2 wheels are 17x7 +55 front, 17x8.5 +65 rear

 

So since my fronts are 17x8 +45 i can go bigger then the 215's you were talking about?

 

The wheel can take a wider tire. The question is how wide can you go before you rub.

Without fender rolling, the "Wheel Fitment Guide" stickie (worth having a look at) recommends +48mm minimum offset for 215's, +53mm for 225's, +58mm for 235's, and +63mm for 245's.

*IF* you were running 235/45-17's (taller than stock) all around, you *should* be able to run 235/40-17's (which are shorter) up front with no problems. It is possible that 245/40-17's *might* work.

225/45-17's would work up front as well, but personally I find that they give a "big fronts/little rears" look when used with 245/40-17 rears.

 

I have the rear rolled and i have the seibon +10mm front fenders.

So your final verdict for size would be?

 

With those fenders, I would think you *should* be OK with 245/40-17's up front, but I can guarantee nothing!

You could dial in some negative camber if you rubbed. You can easily run 2* and more on the street for more clearance without serious inside wear issues.

 

Zdan,
Thank you so much for your time, help, and comments

Im going to try that setup out then and let you know how it goes.

Thanks again!
