i have read and read on how to figure this out but no such luck. What i need to please know is, what size spacer would i need to fill the gap from the wheel to the fender if i am running 8 inch wide wheels and +38 (wtf i know ) i am running 235/40's. i dont know if it matters but it is for the rear wheels thanks.

 

8-10mm

 

ive tried to measure it w a ruler and i get more than 20 mm. i know ill have to roll fenders. but ima try n take pics in th light to show it.

 

Depending on your camber and how low you are I would say a 20mm spacer. I ran a 10mm with a 8.5 +33 (Coupe 19). A 8.5 +33 is 11mm more agressive than your wheel, so overall I was 21mm more aggressive than your wheel. I had a 245/40 tire, about -1.4 camber, was lowered 2.5 inches and my fenders were rolled flat.

 

Look at coupe wheels. 8.5" rear 8" front +30-+35 They're flush at close to stock height (you're at stock)

You really shouldn't buy spacers until you drop the car though, you'll need to buy bigger ones once your camber pulls your wheels.

IMO, you should buy wider wheels with lower offsets.

 

well im dropped pretty significantly. now i dont know exactly what degree of neg camber im running 350z tanabe nf 210 which dropped the front about3.5 inches in the front and the rears on unrevised z springs. i like the look of the neg camber so i dont know if ill wanna align the camber. but yea about the wheels, im ready to buy a new set ( $ speaking) but i just havent found a wheel that i can say ... " thats me" u know
