instead of changing your spring rate why not just get taller springs. If you like the way the car handles, why mess that up?

Ok it looks like we have a bit of a debait goin on. If you increase spring rate you will loosin the car up, stifer springs looser the car, softer the spring tighter the car, the spring length is NOT that big of a deal it will react a bit slower but you are driving a family car that probably weighs 3400lbs. or so, on a race track, you wont be able to tell that much, if it was a light weight mod. or late model you would see a big change. Go for the taller springs and keep in mined that if you liked the way the car drove you did bottom out and hade no rear suspention on the side that was smashed flat in the corner

You guys are gonna love this answer..... To tell you the truth about if I liked the way the car drove, I would have to say yes, with the exception of a slight push going in when its a heavy wet track. As for the bottoming out, I wouldn't even have known if I wouldn't have seen marks on rear end and more noticable was a pinched brake line. Test n Tune I was gonna try upping the springs to 175, 200. Thats what my original setup sheets from Terminator stated so I'm thinking that should take car of it. I was just more curious on what it would do to the handling of the car, more just curiosity for the time being than anything. Still very much in the learning faze..... as you can tell.

when i put stiffer rear springs with the same split on my car it adds crossweight. Is a Terminator hobby pretty light?

The lightest i'll run on the back is a 200,if your car was really light you would have no problems.

Spring rate is spring rate. A spring rated at 200lbs is 200lbs no matter if it is 2 inches tall or 200 inches tall. Once you get the spring preloaded it takes 200lbs to compress it 1 inch.
If you have a 200lb spring at 10 inches and you cut it down to 9 inches then it will be stiffer. The rate is determined by coil wire diameter and the amount of LIVE coils.

Shawn,
You've got a Terminator.Advice is free and dished out willingly.Call 1-515-832-4937,ask for Mark and you'll get more info than you could imagine.Sold one of his Hobby Stocks in Wisconsin last year with Mark's springs in it and it won 12 features.

Rate is determined by wire diameter, outside diameter, and live coils.
but a shorter spring will react as if it was stiffer and it will react faster.
i am not making it up. i went to racewise school put on by afco and thats what they repetead about 1000 times.

Thanks Bryan, I know that Mark will help out, he already has on alot of my other questions, why I didn't think to call him right away is beyond me. I think my brain is frozen with all this darn cold air!!!
