The suspension is springs only. We used 5Zigen but had to modify them to fit. We were planning on Whiteline but they didn't come in. The tires do not rub at all. I will get the offset tomorrow I have it at work.
The exhaust is made by Powertone it is a catback. We will be offering that in 2 weeks.
I have the BPM on order for me also.
The rear wing everyone really liked.
I can't decide on C-West or the Zero Sports air dam wing adapters9 they raise the wing.
