i was wondering if anyone out there was running a rear narrowed 2.5'' and a wheel with 5.5 b.s.? i just wanna make sure everything is gonna tuck nicely and look clean. i'm gonna be running a 325/50/15 on a 10'' wheel.

thanks guys,

If you narrowed 2.5 per side, you will need a 5.0 backspace. I had a previous Formula rearend narrowed 2.0 inches per side, ran a 5.5 backspace on a 10" wheel. Pics here: http://www.fquick.com/garages/Pontia...mula/1998/298/

The guy with the bright green metallic single turbo ta has 325's, narrowed 3 inches each side with ~5.5 Backspacing.

thanks! i saw gator's car,https://ls1tech.com/forums/showthrea...light=narrowed , and thought that running a 5.5'' b.s. with a 2.5'' narrowed rear would effectively be the same as a 3'' narrowed rear + a .5'' spacer?

Figure if we typically run 15x10 with 7.5 bs on a stock width rearend, then if you shorten the axle by 2" on a side that means your backspace on the wheel needs to change by 2" also. So, 15x10 7.5 bs becomes 15x10 5.5 bs

While a 2" narrow/side with a 5.5" BS is common, some would like the wheels to set in farther (like me) to get the car lower. I recently had a conversation with Gator about this exact subject. If you do not mind extra cutting, you can run 2.5" to 3" narrowed per side with a 5.5" BS. It all depends on what you are trying to achieve. Happy cutting.
