Something else I could do legally for STS. Does it make a huge difference?

 

Hypercoils are excellent quality race springs, I know the people and company pretty well and that is the spring brand that I use on my racecar. On the otherhand, changing brand alone won't change your performance really and most will acknowledge that the Eibach ERS are cheaper, more common and basically as good (a real hair splitting thing when hairs don't really need to be split most most of the time). If you are looking for a performance improvement, working with rate changes is going to get you much more than changing brands unless the brand you have now is simply not trustworthy for quality and consistency.

Most really high end teams (F1, CART, IRL, NASCAR, etc) tend to use Hypercoils more often but for normal folks playing with their cars with less budget the Eibachs are plenty fine as well. I think Hyperco has like a 35 year or so Indy 500 win streak going, pretty respectable stuff.

 

i was able to pick up my 700lb and 600lb hypercoils for about 200 shipped

 

Someone on the SE-R forum put together a deal with Hypercoil for some special springs for SE-R and NX2000s. Didn't lower as much as others (SE-Rs are know for limited travel) with higher than average rates. Reports are that everyone is very, very pleased with them. Sounds like a good company.

 

I couldn't get 'em for 200 but I *think* my Hypercoils (for the S) were roughly $70 per spring.

 

Although we generally don't sell springs, we offer Hypercoil springs through the KONI rebuild shop for customers who need springs with their shock work. $200 including freight is an extremely good price as about $70 each is their standard racer price.
