Thanks I appreciate your answer. Kind of a scary thought riding around with no spare,
What I've found is that every time I've picked up a nail the TPMS helped me and I was able to drive home and then take the tire/wheel to get patched.
I recall someone mentioning in another thread that the difference is the included spacer. I assume the spacer size is the same but the bolt lengths are probably different. Probably best to call the company and confirm.
They responded that the spacer is different. You are correct that it's due to the bolt length - they provide a 3" spacer for the R. They don't know when they'll be able to source that again.
Someone is smoking something. The offset for the GT350R is the same as the base. Takes a 1” spacer on the front.
Yeah. Bolts may be that long but not the spacer. That should be 1” regardless of R or non-R.
Remember the R has those carbon fiber wheels. They have really thick mounting pads, so the R has really long front wheel studs and very long rear studs. So the R kit needs much longer wheel spacer. Would seem to be easier to have a slip on spacer and use the factory lug nuts. Might need different t spacers for front and back.
Regardless of the thickness of the wheel mounting pad, the backspacing difference front to rear is 1”.
But this kit uses the stock lug nuts. So in order to facilitate this requirement of their kit, they are using thick wheel spacers. It would seem easier if they included 5 open ended lug nuts for use with their spare tire, so only the smaller 1 inch spacer for the front is required.
I have the Automotive Authority spare and it only needs a 1” spacer to use on the front. No spacer on the rear.
