Summit has Koni shocks on sale so I picked up a pair for the front. I was running Calvert drag shocks up front. The Koni shocks make the car more stable on the street and they do a better job of soaking up little bumps in the road. I'm sure they'll slow the car down a bit at the track but I'd rather have something that is stable on the street than super fast at the track. Not sure why I put the drag shocks in the car in the first place, guess I had them sitting on the shelf so I figured I'd use them. Doesn't seem like a good choice now that I think about it.
