I just bought an different car and I was wondering what kind of springs you would run. What is the rate in the spring pull bar also? It is a two link that weighs around 2200 without driver. The track is about normal. Starts out nice and tacky in the heats and then turns somewhat dry, but not always. Should I switch springs for the feature, when it gets dry? It does happen to get rough from time to time. Any info would be a great help. Thanks

I run a 600 lb pull bar spring.

As far as the corners, is it a metric frame?

Yes it is on a metric frame.

We run a fast 3/8 mile that stays pretty good but rough. Some run LF 850 and RF 950 as a minimum. Most run closer to 950 1050 with a metric clip. I know it sounds like a lot but, it is what it is. As far as rear springs, I ran a 150 on the RR and a 200 on the LR. My RR was so close to the tire that it rubbed at times with a 4 off wheel. If your spring is inboard more, you will need a bit stiffer. On the track it is easier to tell by just setting your rubber markers on the shocks. I like 3 or 4 inches on the rear and 2 to 3 inches on the front.

With cars and tracks being so different, the only way you can really determine the right rate is to read your shocks and have someone that knows what they are looking for watch your car as you race.
