ive decided i want to build my own coilovers since its cheaper and i dont have the $$$$ to buy hack/ weld a setup. so i want a stock ride height for dd but have the option of lowering it for track/ auto-x. all the springs ive seen so far are around 6" some even shorter if u really want to slam it, the po already hacked off the old spring perch and put in adjustable perches with a 6" spring. i have the perch maxed out and the spring sits in there very loosely which i really dont like. if i ever get air born this means the spring will be tossing all about which cant be good. the solutions i came up with were swapping the spring out for a full length spring which would be around 10" but i cant find any anywhere? I could buy spring helpers which would hold the spring in place but even with the perches maxed it still doesnt sit back at stock height would the helpers help bring it back to stock height? the only thing i can think of for what i want is to have some springs custom made which sounds expensive. I dont even know who could do that? has any one found springs that work for this or has had luck with the helper springs?

What's jour budget? Cuz without speaking about shocks, the groupe control coilover conversion look preety good. Someone told me about a company doing springs at diff�rents rate, heigh, diameter etc... Can't remenber the name

i want to keep it under $1k shocks must be mono tube and rebuild able. springs im still debating on rates, 200-300 could good for middle of the road. this is going to be a dd and autox/ rallyx. i know auotx and rallyx are polar opposites when it comes to suspension but i wonder if anyone has found a good in between for both...

i maybe asking for too much but it cant hurt to ask.

Under 1k �? You can easily do your own kit i think. The web site i was talking about is Faulknersprings. You can find � lot of differents springs and with � little work you' can concert the front info coilover quite easily. I'm going to build my own suspension using their springs. Also have bilstein b8 that are'going'to be refurbed and harden a little

4 springs is about 150�, more or you buy thje seats to match the spring at the same time, I will make mines to suit the car as i don't want adjustable height.
Then find 4 bilstein or koni and you will start to have a good suspension.

Or you can buy � ground control coilover conversion kit. Is about 400$ iirc and then p�t th� shocks you want

Faulknersprings is a great website! this is exactly what i was looking for thank you so much and for custom springs their prices arent too bad either. now i just need to figure out what would would be a good spring rate for rallying/ auto-x? so im looking at putting together bilstein hds on all 4s with 10" free length springs up front/ 6" fl springs in the rear and 2.5" adj perches all around so i can have it at close to stock height when i want it or lower it for street handling. this is where im got my info for stock m3 spring fl http://www.r3vlimited.com/board/showthread.php?t=244597 if this doesnt seem rite someone please give me the correct info but it sounds like its in the ball park. if there any other spring companys that can build custom springs at a reasonable price let me know thanks for the help.

I'm building coilovers soon. I have the parts but I'm too swamped with maths at the moment to work on my car so I'm driving around on stock springs and freshly blown front struts

I got some generic adjusters intended for Hondas on eBay, bought Koni SAs on TireRack (on sale!), and got 450lb 6" front springs and 650lb 5" rear springs. I did a lot of research and concluded that with springs of that rate and length I'll be able to maintain a good ride height (1" or less below than stock) and seriously improve handling for my purposes (street and autox). I will be keeping the stock swaybars. It may be a little stiff for most, but I prefer a stiff, controlled ride because motorcycles spoil you like that. I have driven a car with the H&R sport/bilstein sport combo and it was nice for a street car, but I found it a little soft. Keep in mind that most good setups put the rear springs at 1.4-2x the rate of the front springs. This is due to the suspension geometry, which alters the effective rear rate quite drastically!

You can get some helper springs if 6" are too loose in the front for your tastes, but if you use helpers in the rear, they must be welded to the main spring, otherwise they can just fly out at full droop due to the spring configuration.
FWIW, the static height of the stock rear spring on my car is 5-3/8"

I got my rear springs here: http://www.racingsprings.com/
They have a pretty good selection, but I found my fronts on clearance elsewhere and saved some $$. If your budget is better than mine, I would recommend buying Ground Control's coilover conversion kit, which has higher quality adjusters, and comes with ground control's support, warranty and assistance in making your spring rate choice. http://www.ground-control-store.com/products/description.php/II=121/CA=241
