Hi gents,
I'm looking into building a 289 USRRC car in the near future (well, once I check one out at the FFR Open House next month) and I'm going through the usual pin drive vs. five lug debate. I really like the pin drive FIA wheels from Triago and Vintage Wheels but I also wanted to run IRS. On top of that I've been reading about all the complications of getting the front suspension to play nice with the pin drives from a control arm length/spindle/geometry perspective. So I'd really appreciate some input from the guys who've actually gone through this internal debate and hear what you decided to do...
I'm wondering:
- is there a big difference between running the solid vs. IRS rear suspension (since it seems the narrowed Moser rear seems to support the pin drive wheels)?
- was it as hard as it seems to get the front suspension to work with the pin drives?
- or did you just opt for a more "standard" wheel and avoid all of the complexities?
Thanks a bunch for your input!
Rob
