yes, the santuffs are way up there as being the best. koni double adj's were great for many years and still are nice. for what your doing, I wouldn't 2nd guess them. I use them and work great on my 8.50 car and I also use the Penske's on the 9.30 car. shop around on price, summit wants too much. I think tim mcammis race cars are around 399.00 ea.
