Hi everyone - Mr Speedline here - new update for all the guys who think all they need is RSR spec Speedline wheels for their car to be happy.

We know they are 11" in the rear, and can figure out approximate sizes, but there is nothing better than building a test wheel and bolting it up. So much theory is proven incorrect with a wheel built and mounted.

RSR wheels were built with center locks, and the offset I suspect on the wheel centers is completely different than our standard rear Speedline wheel centers.

I test built a 5.25" inner, .25" crush, and a 5.25" outer making a 10.75" close right?!

Test car is my convertible that is being converted to a widebody. The 930 rear flares are attached, the trailing arms are NA not the rear turbo arms, should allow wider wheels to fit.

Pictures speak for themselves. The combination does not fit. No way will it fit.

I am also including pictures of a Techart Speedline wheel that is 11" wide 7" inner, .25" crush and 3.75" outer -- picture says it fits.

Your standard 10" rear Speedlines for 3.6 Turbo is 8" inner .25" crush and 1.75" outer.

Jim,

Is your car a narrow body 964? The ET5 offset x 11" should fit on narrow body trailing arms but not on the turbo arms.

Thanks for the great info Jim!!

Guys take a gander at my thread.

I was all gung ho until Adrian thought otherwise.

Jim, take a measure from the frame to the outside of the fender. We can make sure we are apples to apples.

Also it should camber in at the top a bit when compressed, but not enough to fit that deep lip.

Edit: Just measured and I have a short 14.5" from the frame to the outside of the fender.
