Brz Drag Setup - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

For those who are interested in making these into 1/4 mile cars(Yes they are out there) What is the widest tire you can fit in the back of these things? Will 315's fit? 305's?

JoeBoxer · 09-11-2012, 10:56 PM

Probably as wide as you want if you don't mind it sticking out the fenderwells or are you talking about inside the fenders?

Wider past the point where the grip exceeds the torque doesn't help. Find out what sort of HP/Torque you plan to get out of it and select your tires appropriately.

Id like it to be as flush as possible.

Tansey86 · 09-11-2012, 11:01 PM

Well I haven't seen anyone go past 255's and you're gonna need more than that if you turbo this car and run upwards of 450rwhp.

Zaggeron · 09-11-2012, 11:11 PM

I find 450 hard to believe out of this engine -- though I guess you could get it ... once or twice

I probably wouldn't be that surprised to find out I'm wrong though ... In any event, you are not getting that at launch RPMs I presume and wider is not always better for drag racing

Tansey86 · 09-11-2012, 11:14 PM

This car has already made 460rwhp+ lol. Has been for a few weeks now. DD'd

JoeBoxer · 09-11-2012, 11:14 PM

I'm not 100% sure but i think you could probably get a 275/40R17 Nitto or BFG Drag Radial back there as long as its not lowered very much. I don't know if its neccessary though because those power numbers are so high in the powerband.

Probably a little early to assume that 460whp is reliable for a DD...then again everyone's idea of what constitutes a DD is probably different...

I didn't mean it was reliable, was just saying that the power was made. I have a feeling that engines a time bomb at the moment. I've been pleasantly surprised with this motor though.

Widest ive seen on a stock body is 275.

Calling something a "daily driver" usually means it's reliable and livable on a day-to-day basis...

Well up to now it has been. Sorry I guess I should have said its made that power but its reliability is still questionable.
