Koni 8040 1353SPORT - Sport Yellow Shocks

Rears started chipping powder coat after a year. They are rusting already. I only drove in the summer. I need to send them in for warranty

Performance

Better Handling

Koni has a great reputation for quality and performance, and this coilover kit seems as though it's a great value. I feel that the components are of good fit and finish. I'm glad to have ride height and rebound adjustability, and I believe it'll serve my purposes nicely. The car looks so much better lowered, and the ride height adjustability allows me to fine tune the corner height. I wish the kit had compression adjustability in addition to rebound like some other similarly priced offerings. KONI themselves have told me that the spring rate on this kit is a bit soft - if I need to stiffen things up in the corners, that I might go for an enlarged rear sway bar. Additionally, I expect that a haldex controller will result in better overall dynamics. All in all, a nice kit and a good brand. Not sure if I could have justified another 700$+ for the Bilstein PSS10s that I'd been considering. They look great too - mirror polish, grey springs, and red anodized front spring perches and locking rings.

Lowered ride height for asthetic improvement as well as imroved handling

It was pretty straightforward. Helpful instructions put out by ECS Tuning.

Spring rates almost too soft it seems... But good ride quality.

Quality and reliable.

Better handling

Routine in my opinion

Exceeded expectations

If you want more than 2.25 inch drop , this is not for you.

KONI is one of those names in performance that you instantly recognize because of how good their products are.

Increase handling ability, increase bump stiffness, decrease body roll, lower the ride height, and just make it turn better all around.

Installation is the same as any coil-over, it takes some time and effort but its not super difficult.

This is a wonderful option for a suspension upgrade. It pairs nicely with a host of springs from Flyin' Miata, Goodwin Racing, Eibach, Progress, and more. The best use for these however are when they are paired with Ground Control's Coil-over conversion kit. It takes this shock to the next level.

GroundControl's Coil-over Conversion is highly recommended for this Shock Absorber.
