Fits good! Everything went together we'll. It's kind of confusing figuring out what height you want but it's nice to separately adjust ride height and dampening. Would definitely recommend this product if you're over the fence and kind of scared cause it has no reviews. Only had it a few days but will update if any problems. ... show more

    • Avoid these, they fail!
Model: 05-10 All Mustangs
I purchased these for my 2006 GT. The installation was pretty straight forward. They have been on the car less than 8 months and less than 20 miles driven, the left rear shock has left a puddle of pretty blue oil under the car. Failed product, not happy...

    • Good coilovers but no instruction
Model: 15-23 Excl. MagneRide
So I've had the coilovers installed for maybe 4 days and so far they're pretty decent. Even in the hardest setting of the damper isn't the worst feeling ever. I drive a 2019 mustang and I'm sitting about a coke can off the ground on these. They do seem to make a little noise and they settle but ill wait about another week on that. Only thing I did not like was the fact that they did not send the bottom hardware to bolt down the rear struts. I had to buy hardware for the rear. Some instructions wouldve been dope too. Oh and some instructions on the coils adjust would be great also. For the mustang the coils adjust at the spindle at spot that attaches to the hub in front so that means u cannot adjust the ride height of the without taking off the wheel and the entire front strut assembly. Definitely a pain when adjusting the front. ... show more

    • Small but fixable issues at this price point.
Model: 15-23 Excl. MagneRide
So far fitment is on point. Adjustability is amazing, however my right rear shock adjustment knob is stuck in the hardest position (seems stripped as it just keeps freely spinning even after fully tightening the nut under the adjustment knob) and the included front sway bar end links keep coming loose so I’ll have to change those nuts out for a different type. Other then that it’s a very good set of coilovers for the price and the second set I’ve owned. I gave three stars because other then those two issues at this price point I’m not really mad plus I had ZERO issues with the last set I had on my is350 so I know the quality and reliability is there. ... show more

Had these installed professionally and this is the 3rd time that the right front sounds like it's going to fall apart when you hit a bump. Car has never been in rain or snow and never made these noises before. Naturally the 30 day return policy has expired. I would not recommend these to anyone. This is the second review I've written, the first one was not allowed for unknown reason? Lol ... show more

    • The vehicle is to heavy for this setup.

No matter what you do this vehicle is to heavy for these shocks. We have tried everything to keep this car from bouncing. Nothing has worked.
