ISC Suspension® - Street Sport Series N1 Basic Coilover Kit

I installed this on my 2012 Mazda Speed 3, fitment was perfect and installation was mainly doable (the old front sway bar end links where very corroded and required help from a mechanic) I installed the rear in my garage mostly alone. The suspension is well made and high quality, very adjusted. There is no camber adjustment on this set, lowering my car about 1.5" (note the speed3 sits lower than a regular 3) gave approximately 2.5-3 degrees of camber, still functional. Car rides great as a daily driver, even on bumpy Michigan roads, dampaning adjustment makes a big difference. I highly recommend buying anti cease to coat the threads and lots of WD40 for removing old suspension. So far I am very happy with this product.

This suspension kit was very well built, quality was not the issue. The parts did not seem to be the same as the ones pictured in the catalog, so I called and spoke to Jason, who assured me that I had the correct kit, and shared some helpful hints after he found out that I was planning on installing it myself. Well, all went well on install weekend, even though there were no instructions shipped with the kit, the car is back on its tires on the floor and looking ready to do my favorite winding, hilly road runs come spring. I will try to remember to send some pics when I get it out. Thanks, Doug.

No issues with the product but if you increased your wheel/tire size width over the stock size, then consider buying some wheel spacers so you don’t have a rubbing issue.

So before i go over the ISC coilovers i bought for my GTR i just want to let any potential buyers know 2-3 weeks lead time meant 8 weeks lead time so keep that in mind. They ISC coilovers look nice with the gold and black look. The design seems simple and the construction seems okay. The ride so far seems good, it rides stiff but doesnt beat you up and when i hit bumps it stays planted. I havent played with the adjustments much. But i do have the front at 17 and the rear at 14. I figured generally in the middle of the 32 steps it has would be good. I did have the street sport ordered in my case. Over all im happy with how they preform but extremely disappointed at how long it took to get them.

So just purchased a Z4 3.0 to replace my Z3 2.8 - all original suspension on it. As you can imagine the suspension was in need of replacement. You could really tell mostly going off and on, highway on ramps (the cloverleaf). The front end would really dive down going into the turns at speed. The Z3 had upgrades, but I went with KYB shocks and H&R springs. This time I decided to go coilovers. Through my research I discovered the ISC brand. Looked like a good value but not a quality compromise. I chatted with a rep about my daily use. The rough streets of the Washington, DC metro area. Always under construction! He said the street comfort would be the right product. And he was dead on! The Z4 is already a stiffer riding car than the Z3. I wanted to lower it a bit (about 1 1/2") but not suffer to much. As an athletic 55 yrs old i'm not brittle and not looking for Cadillac smooth but i don't want racetrack stiff either. These are perfect. The ride is better than factory stock. I have friends who put original back on theirs. This is better. As I said the streets aren't the best and these are very very tolorable considering that. They are well built and have a great warranty. As for the company, I had a few challenges during the COVID-19 issue with production and delivery time. But they got me the product in a good time. I needed a different set of rear components, because the warehouse shipped E89 rears instead of E85. They had them to me in 48hrs. No questions asked!!!! Everyone I've dealt with at ISC has been super nice and super knowledgeable! I totally recommend the product 100% to date. I've been driving on them for about 60days now. And am super satisfied with the purchase! Good luck and happy motoring!

Very extra good suspension for my Honda. It's better or OEM. Very good service for Quebec, Canada. Thanks!

Ride quality is perfect.

I didn't think the drop was gonna be so substantial. At the highest setting I still rub fenders, but I still love it.

I actually love the suspension, it rides great but the front sounds to squeaky to be be brand new. Hopefully the sound goes away. :/

I’m satisfied with the service, had a few questions before ordering, called CARiD and got answers to all my questions. No problems with delivery either. My car has become more comfortable and even abrupt turns seem not so sudden.
