stock 17's good for road racing
 

im new to road racing. I have 19inch ADRs but im buying nittos to put on my stock 17's to use for track only. the car is lowered. i have 15mm spacers on the rear. i have a few other suspension mods done. is this a smart choice or no? thanks for your help guys.:dunno:

Why not?..... A better option would be to get lighter wheels I guess.

this is true but i thought 17 would be too small not wide enough for the rear but i guess if i get a good enough tire.

Wider is better...BUT for the price difference in race tires for 17 vs 19's will likely allow you to buy better rubber.....

only thing I can think of is give it a shot, if it doesn't work for you you'll likely wear out the 1st set of tires in a season, and you can try something wider.

You'll be fine with the stock 17s. I actually bought two sets and used the four rear 17x8 rims. I mounted 275/40/17 tires on them and used this setup for autocross & road course. Inexpensive way to get started since stock 17 rims are common and cheap. No issues at all -- I used 20mm spacers in front & 25mm in rear to flush them out.

Here's a picture of my Z with the stock 17s (rims were powdercoated black) & 275/40/17 Hankook Z211 race tires:

That looks good z-u-later. What color did you paint those rims? Is that gloss black?

thanx guys..it is the cheaper way especially since im jus starting out.little by little you know.

Yes, they were powdercoated glossy black. I usually get double-takes from other drivers asking if they're aftermarket rims. :icon38:
