Small bolt vs. Big bolt

You would be fine with the SBP but just realize that they have limitations. If you are okay with that then keep the SBP. I kept the SBP because I already had my SWS wheels and did not want to purchase a new set of wheels/axles/brake backing plates, etc. I too have the SSBC kit so I could run either pattern in the future up front. Changing to new quality A-body large bolt pattern axles is not cheap either. You can have yours redrilled though. The SBP should hold up to 400-475hp no problem. I had the same question about a year ago.
