A couple of years ago, in order to shave weight for hard tire heads up racing, I replaced my front shock/spring combo with a set of Viking double adj coil over springs. It seemed like a good idea but I now wonder if that was a mistake since I have a lower HP car (425 on motor, 605 on n2o), would I be better off going back some Moroso trick front springs and a good set of 90/10 shocks? The car weighs 3280lb with 1710lb on the front.

Santhuff Springs and Viking DA would be my choice.

I went from Moroso trick springs and Calvert 90/10 shocks to Viking bolt on coilovers this past winter. With the Moroso springs, my car would pop the front up then drop it quickly and actually bounce the front tires a few times after launch. Also, the front suspension would be fully extended all the way down the track. The Vikings are a huge improvement on the street and track. Weight savings, ride height adjustability, compression and rebound damping adjustability.....what's not to like?

Coil springs and a good shocks.

I have two Pontiac buds running pretty quick with coils and good shocks.

One runs 9.50s,the other high 7s.

Both on small tire.

I'd like to hear more. Type of lower a arms, modification required etc. I have a set of Santhuffs I'm gonna have to replace with something soon. After 10 years, but not a lot of use, they've sagged some. I've considered a coilover conversion, but not heard a lot of great experiences.

I'm still using OE upper and lower arms. The kit I bought uses a hybrid spring. The upper end seats in the OE spring seat and the lower end seats on the shock body. The installation was fairly straight forward. I did have to drill out the welded "nuts" in the lower control arms so a 3/8" bolt could pass through. I also had to enlarge the holes in the subframe where the shock body passes through. I think over the winter, I will remove the lower control arms and reinforce the area where the shock cross bar mounts since that small area now supports the weight of the front end.

I let Mike Proulx at Viking select the springs and shock damping for me. He has been very helpful. One of the reasons I went with the hybrid coilover set up, is because it allows easy access to the adjustment knobs on the DA shock. I use different settings for street and strip so I adjust them quite a bit.

Thanks for that. I'm gonna check into it further.
