i have a 89 camaro 355 dual plane 236/244 duration at 50 with 488/511 lift 11.1 compression ported sportsman 2 head with 2.05 1.60 valves i have all sphon rear set up with air bags and iroc springs would 90/10 struts and trick springs help

 

do you have traction issues now? If yes then I would do the 90/10s then first, then trick springs afterwards after checking traction again.

 

i dont have the engine in the car its still being build but i want to make sure i dont have traction problems

 

I use Koni SPA1 front struts in my car for years. They're not cheap but they're better than a 90/10 strut.

Until I finally decided on installing trick springs, I was using V6 springs for a number of years. The original IROC springs have a real heavy spring rate which means it takes a lot to compress them. The V6 springs are made with a thinner wire and have a softer ride. They can be compressed more at ride height so they have more travel when the front end lifts. You could also use an RS spring or find a pair from an 82-83 with a 4 cylinder.

You don't want a spring with a heavy spring weight unless you're corner carving. For straight line acceleration, you only need a spring heavy enough to hold up the car at the preferred ride height. Adjustable shocks do the rest of the work.

 

no way to tell if you have traction problems until you get there, so save your money and then take it to the track

 

FWIW... I wasn't having traction issues but still installed 90/10's and springs in my ride. didn't notice it going much quicker, but, it did feel better on the launch afterwards.

 

I think they are worth it. I couldn't get my car to consistently hook until I installed the trick springs and Koni SPA1 struts. Like someone else mentioned V6 springs are also an option if you are on a budget.
