DNA MOTORING 4PCS Suspension Coilover Sleeves Spring Kit Compatible with 88-00 Civic / 93-97 Civic Del Sol / 88-91 CRX / 90-01 Integra, Silver, COIL-HC88-T11-SL

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.

Was expecting cheap, bad quality stuff. But was very surprised when the car is riding much better than expected. These help lower the vehicle by about 4 inches if desired. Great for the money.

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

Does not fit my 96 honda del sol...

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!

Had to use a spring compressor to take apart the stock struts. Once mounted, the car seemed to sit very uneven so I had to adjust the coils to make it sit level. One thing that is VERY important is to make sure the set screws are installed evenly and very tight. If they come loose it is almost impossible to adjust the spring. These springs are also going to be way shorter than your stock ones so you might need some kind of spacer to keep the new springs in place. After 1 month of daily driving one of my top hats broke but its no big deal. This is good if you need something temporary while saving for legit coilovers. I would not recommend these for tracking or autocross, the quality is too low for that.

Excelente producto

I bought this kit to put on my old mustang. I threw the springs away and used the rest to convert my rear shocks to adjustable coilovers. It worked great. I spent $42. instead of $250.Thanks

Llegaron bien y de buena calidad para el costo recomendable

Good

Solid product for the price. Major visual mod for such a small amount money. Good build quality and comes with everything pictured. If you want to lower your car like hella low but don't have the funds for the big brands, this is your answer.

Buen producto se adapta alas. Necesidades

Really happy with the quality of this product for the price , the review with specs /sizing was super helpful , used these as a front coilover for my 1990 Suzuki carry Db51t mini truck , kept oem strut and added these in and fit is perfect , got a adjustable lift now and harder spring so no bottoming out , so happy
