Exclamation What's wrong with my Coilovers?

I recently bought some slightly used ST coilovers from BAV AUTO Recycling and I got everything but the rear spring adjusters. That means I'm bottomed out in the rear and not the front. My ride is worse than when I had my blown suspension...

Will buying rear spring adjusters most-likely stop this or should i refund..

My ride is very stiff my spare tire basically jumps over decent bumps.. ridiculous....

Get them to give you adjusters. Why did you install an incomplete suspension system?

go back and ask them for the spring adjuster like previous post stated. if they don't give you it then i'd refund and buy brand new coilovers for less trouble.

as for stiffness, you can change the damper, i believe there's a knob on top of the strut that can reduce the dampers.

I have asked and they can't because the kit they sold was as is w/o rear adjusters... And Do I need to take the strut off to adjust... and ST is giving an estimate of $140 for a set and Raceland is offering $70 for a set, theres a 1mm difference in spring diameter.

Get the proper size. 1mm is a lot when you are talking about forces over 1000 lbs.

I'm shady with spending $140 or more for something I'm not guaranteed to know will fix this..

So you think that it will help my ride because I won't be bottomed out correct?

You're missing the threaded mount under the rear spring right? If so, that's like an inch added at minimum height setting.

i forgot to think of the 1mm being important to the forces on it.

because i must have forgot to "submit" earlier my post. i said 1 mm being so small (basically the thickness of a dime) in the difference in diameter of the spring perch i can't see it being a problem. just that to be sure the spring perch is wide enough to hold the spring on and not slide part of it off. also more importantly is that the interior diameter of the spring perch is enough that the spring clears it. too much "slop" and it'll dangle when unsuspended and too close it'll clack on it when it shifts.

i would look at each company's design to see if something could be an issue with the spring seating.

if there is still doubt go with the one that's made for it

with that said what size you need?, TMS sells the H&R ones for $80

i would also be certain that your "used", "as is" suspension isn't blown or damaged. that alone could cause it to perform horribly. also how exactly is that spring being held in place now, from the stock rubber pads prong? does it really fit snug or does it move around, that could be your problem too. lastly if your rear suspension is dumped past it's limits and the front is higher, it's going to react poorly front compared to rear.

It's deff in there snug. The diameter size on the current ST coil spring in the rear is 61mm

I have ST coilovers my ride feels great. Get the piece. Who told you it would work without it? There is obviously a reason why they come with the kit when you purchase it right?

I was in desperate need for suspension and bav auto had this kit for $500 shipped and I didn't think I could find a deal with a 6 month warranty like that. The set came from a dinan so I figure they were well taken care of and they deff look like it

Get the piece. Then you dont have to worry about anything. Thats the piece that actually adjusts the spring by the way. Take picture of what the spring is sitting on from the top please.

If they're the type that sit on the bottom of the spring perch, I have a set that I bought for my pss9 kit but didn't need. If they'll work, I'll let them go cheap.

Whoa whoa whoa WHAT? You paid $500 for a used, incomplete kit when they're only $300 new? You can't possibly be serious...
