RCR MK1 Spring Rates

[Phil G]

RCR GT40 MK1 351 with QA1 500lb rear springs and 400lb front. Front seems to be fine however rear seems I little too stiff. I am considering going to 400 or 450 on rear. Car is for road use only and the roads are not in very good shape. Anyone using 400-450 springs in rear?
Thanks
Phil

You can see what I did to copy Chuck and Ryan here.

They are a little bit stiffer than what you already have. Playing with the shock settings allows a pleasant ride for spirited driving.
