coilovers vs cup kit

Hey guys, I'm looking at doing some suspension work to my e92. I was wondering the differences in handling/ride quality between a nice cup kit set up to a cheaper pair of coilovers. Obviously a nicer, more expensive set of coilovers would get everyones vote but I am not looking to spend more than $1,000 for parts. I track once a year max but still want to have the car handle well. If I went with the cup kit, stiff would be set for the struts. I had ST coilovers on my e46 and loved them but have never rode in a car with a cup kit to compare.

Thanks

I thought cup kits are cheaper than coilovers!!

Check out **********s H&R cup kits. They have Touring and sport styles depending on how low you want. the listed price is $695.

Yes, they are. I want to know if the $200-300 price difference for a cheap coilover set up would be worth it since I don't want to spend more than $1,000.

For under $1k just buy the Sonic Tuning S1s. I've had them on the car for about 2 months and I'm VERY happy with them. Love the stance the car has now!

I'd recommend you simply do it right the first time and to go with a coilover system. Seeing how you've had experience with the Suspension Techniuqe V1 coilovers by KW on your E46, that would most definitely be the system that I would recommend for you as well on your E92. The answer is simple, you get what you pay for when it comes to vehicle suspension. As such a crucial component of your vehicle, suspension is definitely something you do not want to cheap out on. KW is known for their reinforced and durable suspension components. KW's coilovers have been carefully crafted and designed by studying the flaws of competitors and improving on them. In addition KW coilovers can go lower than just about any other brand and allow you to set your car to a "slammed look", "sporty look", or anywhere in between. In the unfortunate event that anything should happen to your coilovers, KW's warranty backs all their products from manufacturer's defect.

Coming from the makers of KW suspension systems the only main difference between the ST Variant 1 and KW Variant 1 is the steel they use. While KW uses Stainless Steel for their shock housing, ST uses Galvanized Steel. However, this does not mean a drop in quality, durability, or appearance. Although coilovers that use galvanized steel are more prone to corrosion due to environmental influences (i.e. mixture of salt water); those in the lower states: California, Texas, Florida, Nevada, etc. don't have to worry about corrosion. Those in the mid to upper States that snow still don't have much to worry about as long as they do not drive in heavy snow conditions upon where salt is used on roads. to further ensure those with doubt about Galvanized Steel, ST has corrosion resistant zinc plating on all of their threaded strut housings for further protection. I'll go ahead and shoot you over a PM with more details!

Yep, I still have them. Zero issues and they still ride as great as they did new. Also, just installed another set on a friends e92 and he's happy as well!
