RX7636

I am looking to go wider on the drag car and searched and cant seem to confirm what backspacing I should run. Currently on the car I am running stock FD wheels with a 28x11.5-16 ET Street. I have no rubbing and it hooks good. But I am going with a new setup and need more tire. I will be running Pettit Flares. According to Pettit with the flares you will be able to add 2" to wheel width but keep the same backspacing. I am looking to run a 15x10 which is required for the ET Street 28x13.5-15. I saw a few post by people saying they were running rear widebody and getting away with a 15x10 with 6" backspacing. That is what I am hopping I can run sense that is what is commonly used on Mustangs and easy to find. Just wondering if anyone could confirm it will fit. Thanks

Can anyone chime in with a stock bodied RX7? I saw people saying anywhere from a 4.5" 5.5" BS on a 15x8 running a 26x11.5-15. Can someone confirm that? And since I will be going with Pettit Flares they give me 2" gain. I should run the same back spacing right? So I would just run a 15x10 instead. My final goal is to fit a 28x13.5-15.

Hey, I also just got some pettit flares and want to run the widest wheel/tire setup possible. I don't know the answer to your question but check out this car:







How wide a tire do you think he is running?

Thanks,
