I know you guys have seen this, but i couldn't find any information when i tried searching. No I'm not going to buy these, but i'm wondering if anyone else has.

Those are knock off Ground Control coil-over sleeves. People seem to like Ground Control, so I don't imagine them being much different.

^ BARF... seriously

maybe they should have looked for something to replace those phone dials before springing for the shiznit coilovers

Expect a stiff ride.

for that price its worth a try. You could turn around and sell them to some n00b if you dont like them

Looks Like Generic Brand Of Ground Control But Maybe Worth Lookin Into If You Are Into Stiff Suspension

I picked up a set recently. I'll post up some results once I get the car put back together this spring. They're 8 rear/6 front stiffness wise, compared to 6/4 on the ground controls (though I believe the GC set is progressive). Not soft, but then again, I drive my car 1500 miles a year anyway. Besides, I have to hold that "heavy" V8 up.

My race car needed new spring seats so I bought the cheapest honduh coilovers on ebay just for the adjusters (about $40). They went on a set of QA1 springs that I bought the previous year ($35 each).

My setup cost about the same as this but I got to choose my own spring rates.

The cheap honduh coilover kits actually came with one pair of springs that I could have used. So I could have saved on one pair of springs for a total price comfortably less than this kit.

If you really bust the sellers chops, you might be able to find a cheap honduh coilover kit with all the same spring rates needed for an Rx7 for $40.

i got a set for my daily driver, there bad, dont even bother, i took them off after about an hour of driving, and they blew out my struts

edmcguirk: What methodology did you use when selecting your spring lengths and rates?

Parastie

They're coilovers. Why on earth would you get coilovers for a daily driver?

wockstaur

man oh man those are some cheap *** suspension. if you want to get those, expect your shocks to go out and everything else in your car to fall apart. you might as well chop off springs or heat them to shrink. 'cause $100 is way too expensive for those, since they're all the same, you can find one for a civic which cost about $20 and you'll end up getting the same box. The springs are so stiff, the only thing that raises or lower it is the lil sleaves that comes with it. Every bolts and accessories will fall off if you drive with those around, plus you'll end up with a headache trying to drive it down the street. here's an idea, if you want the "lower look" put a kit on and get bigger rims... itll be better than cheap *** coil over, or maybe lowering springs. but your best bets are coilover dampers.

I wouldn't trust that setup...

My first set of springs were chosen by a local Rx7 racer who sold me several race prep parts and installed my radiator. After asking my driving preferences he selected 350 front and 250 rear.

That was significantly stiffer than stock but the car still required over 5 degrees of camber to get even tire temperatures. After a few years I decided to buy stiffer springs and that I would keep the same proportion front to rear.

I chose 450 front and 350 rear. Later I changed to 325 but it turned out that was not necessary. I left it at 325 but 350 was fine.

To choose length I measured the ride height of the 350/250 springs and I converted the distance to what would be expected for 450/350. (compare 350 free length to 350 normally compressed to get pounds then calculate that weight on a 450 spring to get compressed height)

From memory, I think I decided on 450x7 and 350x10. It was a few years ago. I can't remember my exact reasoning but I decided that longer springs were better when you have a choice. In the front you don't really have much of a choice but in the rear I think you could get away with a 7 inch spring. 6 inch in front might have been better for adjustability but QA1 does not sell 6 inch.

You would only blow out shocks if the springs are too short and the shock bottoms out. Springs that are too stiff might wear out shocks a little quicker than usual but I haven't had any problems.

Neither of those problems are quality issues. You could buy the most expensive springs and have the same problems.

The only differences I have seen are the type of adjusting collars. I have seen set screws, clamp, and jam nut collar adjusters. I like jam nuts but I think that's just personal preference. They all cost the same.

Most of the honduh kits will be too stiff for a street Rx7 because they have a different suspension geometry. They reduce the spring rate through leverage more than an Rx7. I doubt you'll ever see 900 pound springs on an Rx7. But if you are willing to do the research, you should be able to find some popular kit with good spring rates. Look for popular cars with macpherson struts not A arms.

Finally, springs are generic parts. There are very little quality differences between springs.

Even cutting spring coils is a legitimate way to stiffen the suspension but you have to know what you are doing.

You can spend more money to buy a kit someone else designed or you can design your own. Sometiimes it is well worth it to let someone else design it. (do you trust these ebay guys?)

LOL, I'll let you know when all the bolts on my car fall off bud.

Better buy Teins I guess, they're JDM tite yo.

Any recommendations on what to look for if you're buying the ebay stuff to use for just the perches?

scathcart

Your car runs coilovers stock.
What do you think coilover means... spring COIL OVER shock.
Making the perch adjustable so you can adjust ride height changes only that... ride height.
So why not run adjustable coilover perches on the street? The only difference is the ride height.

The problems come when people install insane spring rates on stock shocks or lower their car to the point that the shocks bottom out.

Parastie

Ah right, my mistake.
Still though, i certainly wouldn't choose this kit for a daily driver...

scathcart

Me neither.
I wouldn't choose this kit, period.

There's a guy locally who recently bought these for his 2nd gen Eclipse. I'll take a ride in his car after they go in to see if they're actually as stiff as I think they will be.

I'm actually tempted to buy a cheap set to experiment with.

white94pgt

i have a set of ebay coilovers like that on my probe with stock struts. overall, its not to bad. the quality is good, they are stiffer than stock, but not too stiff. with the stock struts i have, it tends to have a bouncy feel at times, but is not that bad. and thats not the springs fault, its just my old, soft, stock struts. defently worth the money
