Correct offset to accomodate future mods?

[WhatV8]

I've been doing some researching, so I hope I haven't missed anything. I just want to clarify before I purchase my tire/wheel combo. I'd like to mod the car mainly for autox (STX class) with some street use.

I have a 99 GSX, and I'm planning on getting 245/40ZR17 Direzza Sport Z1 Star Spec tires and 5zigen FN01R-C 17x8 wheels. I've also started looking at the Evo 8 brake upgrade. I realize I'll have to roll the rear flanges. I am at stock height right now. I'm not sure yet what suspension mods I'd go with, but I don't think I'll be dropping any more than 1-1.5".

So I'm torn between whether or not +43mm offset is the right choice or would +35mm be better? I think I'm mainly concerned if +43 would clear the Evo calipers.

Thanks for any advice.

I can tell you that +43mm will not clear the Evo Brembo Brakes. If I were you I would get a set of Evo 8/9 wheels which are +38mm, they look good and will clear those brakes.

if you go to the 5zigen website they will tell you which size will accommodate the big brakes for EVOs, STis, and 350Z

5ZIGEN USA official website

Also be a man 8" are weak (so 2006) get AT LEAST a 8.5"; that's the proper size for 245/40 anyway.

Thanks for the advice, and the question of my manhood. 8" is the max width I can have and stay in STX. I did check out the 5zigen site before, and I could have sworn it said the +35mm cleared the Evo Brembos. Guess I was wrong. I'll keep checking for used Evo 8/9 wheels.

+35mm will clear brembo calipers. Ask me how I know, I wouldnt say go any more than +38 on 8-inch wide tires to clear.

Ya know...if ya do decide to go wider...ive got a set of recently powdercoated 17x9 +35 5zigen fno1rcs with used 255 toyo RA1s for sale....

Thanks for the offer, but I'm going to have to stick with the 17x8. Good to hear the 17x8 +35 will clear the Brembos. I really like those 5zigen wheels, and I wasn't looking forward to having to search for used Evo rims.

This thread (http://www.dsmtuners.com/forums/fre...tions/286685-will-these-wheels-tires-fit.html) says there is only 2mm of fender clearance with 245/40-17 tires. Since they are nearly the same diameter as stock, would I only need to worry about fender rub when the car is lowered?

Thanks,
Chris
