what should be the inside diameter, in inches, for the springs?
also, what is meant by 'hypercoil'? (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif) |

depends, what are you trying to do??
stock dia. is approx 4" for the ID hypercoil is a brand name I believe...marketing name, sounds cool I guess (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif) the aftermarket adjustable spring perches use a 2.5" spring (ID) |

the 2.5" size is kind of a "standard" size for race/aftermarket applications....this size allows the spring to be very close to the shock for better packaging.....a spring of larger overall diameter is just taking up "space" and does nothing benificial that the smaller spring cannot do.
(IMG:http://www.914world.com/bbs2/uploads/post-2-1101875042.jpg) in the picture, you'll see a Bilstien shock with a threaded sleeve and collar....the threaded sleeve is slid over the shock, the collar allows one to fine tune the ride height in order to switch over to the coil-overs you need the sleeve, collar, spring and a top piece which holds the top of the spring. What kind of shocks do you have? the cheaper brands have a spring perch that you cannot remove....I highly recommend Koni Yellows, some people like the Bilstiens.... |

I have a set of yellow bilstien rears that have adjutable perches that use the larger springs. They are only adjustable in steps though (has a set of grooves in the shock body, pick a groove that's closest to what you want, not infinitely adjustable)

the shocks in the picture have those snap ring grooves as well....okay for gross adjusment, but not very practical for corner balancing or fine tuning the ride height (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif) |

patrickmotorsports.com offers a nice 2 1/2 inch coilover package for teeners. I am pleased with the one I bought.

no idea on the diameter... eBay has some dirt cheap kits...for $70 bucks including shipping, you can have enough parts for 4 shocks....not a direct bolt-on, I'm sure you'd have to modify the top hat for the spring....

10" free length springs seem to be a good all around choice in length see the post above for the coleman racing products that Nathan posted, those are the parts you need (one pair), I do not know what size or the exact diameter needed....you'll have to measure your shock do you have a stiff front bar or upgraded front torsion bars? 175 is pretty stiff if the rest of the car is bone stock |
