Was just going to purchase a set of rear coilovers from them, anyone ever use them before?

Installed a kit from them last summer on my GT. Pretty happy with them.
I went with the 275# springs (stock was about 250# I'm told) and the ride is very good.

Got another kit for the Indy now (haven't installed it yet).

Thanks for the reply. Order shipped

the rear kit uses standard 2.5" ID 12" tall springs so you can buy them yourself if you can find a good deal...

True - and I checked, but the information is so scattered and confusing sometimes.
Some people use the 8" springs that need to be 500# so they don't bottom.
Others use different threaded sleeves that only work for specific struts.
OFTEN no specific part numbers are given, just "for a Honda Civic"...

It was nice to get everything I needed in the ONE box that FITS.

Yessir, that's why I did it. I went with the 300# Richie recommended for a 3800sc swap, they should be on my doorstep right now

I have 7" sleeves and 10" springs . I originally was going to use 12" springs but they hit the tire with the wider wheels..
I ended up with 375lb springs and the ride is stiff but not as stiff as I had figured..

I ended up using 350# on my '88 LS4 swap. The LS4 weighs about 100# more than the stock cast iron lump but I wanted more road feel and it matches up very well with the Held front coil overs.

Is your Fastback GT's trunk seal shot? My Gen IV replacement GT trunk seals with miter double bonded corners are now in production. $95 shipped to the US (contact me for international shipping rates) More info can be found here GT Trunk Seal Project

What is the benefit in changing to coil overs? More tire clearance, better ride (softer/firmer), adjustable ride height, better handling? Never considered it as my 87 with poly bushings and swaybars seems fine so I'd like to know what the coil overs would improve.

Any and all of the above.

In my case, the lowering springs were starting to sag from age, so I needed the adjustability of coil-overs to bring the rear back up a bit.

Others want to fit the maximum width tire possible under the fender. The smaller diameter of the coil-over spring gives more clearance.

Those with bigger, heavier engine swaps have a choice of springs for load bearing capacity to restore ride height and handling.

Even with a completely stock car, coil-overs give you more choices if you just want to lower it.

What he said ^^^^

AQ1 makes universal variable rate coilover springs, #175-350. That's almost a reason unto it's self.

I second on the great product.. I'm running their koni coilovers in the rear at 300# and I have the front suspension kit (upper and lower A-arms and adjustable coilovers)... I went 25# more than stock on those.. I also have their 1"drop spindles on the front.. On all poly.. Everything rides so nice and planted. I'm dropped about 1 1/2" or a little more... I've had this kit since they were called HT Motorsports and Lee was working there. I think he owned the place at the time?....

I also have their 13" rotor/ wilwood brake kit.. Everything worked great, as well... but I had to modify and weld new tabs for the parking brake caliper to have it slide on.... Originally, the caliper would slide off and jam in the rotor.. Bad news!.. NO more

Actually, the stock rear spring rate is closer to 150 lb/in. Just FYI.
