DNA MOTORING Coilover Suspension Kit Sleeves Compatible with 88-00 Civic / 93-97 Civic Del Sol / 88-91 CRX / 90-01 Integra, COIL-HC88-T11-BK

Works very well, make sure you upgrade your shocks before install as they may blow out and leave you with just the spring holding up the car

Not the shims but the springs are good replacements for wore out springs on an NA Miata if you already have a adjustable struts that is.

Does not fit my 96 honda del sol...

I've waited almost a year to complete a review. I ran into a few issues. I've swapped the springs and collars around in every combition and my rear collars are maxed out and it is very low. No way around it unfortunately. But I wanted it this low so I deal with it. Installation was pretty easy with access to a good spring compressor. Look out for rusted and siezed bolts. Hit all the bolts with some rust penetration of your liking a few times over the course of a week or so. Several of the fasters were tough to get out. It has nothing to do with the product, just a heads up. I drilled out the silver too spacers so they fit but ended taking them out. Extended too hats and this is a amazing value to lowering your car. The ride quality is beyond my expectations. I'm very impressed with all aspects of a cheap set of springs and collars. I added quite a bit of antisieze to the collars for future adjustment. They get very corroded if you don't do it.

So I got these for my 95 Civic I am no means a mechanic but the install was fairly easy I love how my car looks you do kind of throw the easy ride out the window it is quite a bouncy ride kind of feels like you're driving a go-kart but it's not horrible definitely worth the 50 bucks I'm happy with my purchase

I purchased this Item because I needed to convert regular shocks to coil overs on a custom build.Like many others I was having a hard time finding the SPEC'S for this product. So here goes.Large spring (front): O.D. 3.575", I.D. 2.620", Length 6.375", Wire O.D. .480", Spring rate @ 1" compression 450-500#.Small spring (rear): O.D 3.400", I.D. 2.600", Length 6.160", Wire O.D. .400, Spring rate @ 1" compression 250#.Adjusting sleeve: O.D. 2.275" I.D. 2.027, Length 4.730", Thread length 3.835" usable adjustment 3.165", Threads"Square" type (not Acme) looks like 1mm pitch.Adjustable Spring seat nut: O.D. 3.354", I.D. 2.320". O.D. where the I.D. of the spring locates 2.520".Top Spring seat (aluminum disc): O.D. 3.320". top hole 8mm. O.D. where the I.D. of the spring locates 2.435".Most all 2.5" I.D. springs should fit so you can adjust your spring rate and spring lengths to your needs.I am using the sleeves, spring seat nuts and the top disc with a fabricated collar ( to keep the sleeve from slipping down on a regular shock) on a custom golf cart. I myself would not use this kit on any street or race car withoutmodifications and professional help. I hope this review answers some of your questions. Good Luck!

Used on a 1990 Prelude. They work well but if you do lower it all the way your shock may hit the top hat. I could lower probably another 1.5in but I'm already 3.25in off the ground and roads are garbage around here
