I got a true radial efi class to run in this week end. I had some springs to try. Just wondering if they might be worth a tenth.

------------------
86 IROC 406 tpi mass air
trickflow g2 heads
slp runners
stock tpi
about a 272 custom hyd roller comp cam
30 lb injectors
no smog,a/c,or egr
working on homemade chip
running on radials....

 

I put them in my car but can't give a comparisson since so much else was done at the same time. The only real way to say if the help or not is to do a swap at the track. Make a couple of passes with the original springs, then change them and make a few more passes. Runs made on the same day are the best way to compare changes. If you wait a week or 2 between races, weather and track conditions can change and give false readings.

Changing springs is nearly pointless without changing shocks. I seriously doubt you'll see any appreciable benefits without some shocks that will allow the suspension to operate like you want. Even a set of drag springs won't work well without the proper shocks.

 

Changing springs is pointless unless ya change shocks? To a point. Tossing in a set of, say, Moroso Trick Springs wouldn't be pointless....would let your front end lift a bit more than stockers...regardless of whether or not you change your shocks at the same time. Granted a shock change would help launches even more, but aren't exactly necessary.

 

Note the word, 'nearly'.
