I bought these sport springs along with Bilstein sport dampers for my Mazda MX-5. The old dampers were worn out which gave me an excuse for the upgrade. After changing out the springs / dampers I can really tell a difference. Right height lowered ~1" giving a little sportier look without being too low. Handling is also GREAT; the car stays totally planted in tight turns. Definitely one of the best upgrades I've done to date.
Excellent value, and Quality made
I really like it, it made my truck is much more responsive, it stiffens side to side roll well. On my truck it also makes the rear, without a load, bounce when driving over rough roads at an angle, i.e: railroad tracks, bumpy curves, driveways, it is not bad enough to bother me though. All of the hardware and brackets are heavy duty, except for the u-bolt hardware. I recommend this product!
Thick, Sturdy Bar with all the Necessary Parts
Title says it all. This bar is probably the cheapest bar out there for the Celica, but it's still a quality part. It also comes with all the necessary and new installation hardware, which is a big plus. The biggest downside to the bar is that it weighs significantly more than others on the market (and the OEM bar). This modification alone definitely brought the Celica from understeer to oversteer, so mission accomplished in my book.
