Progress coilovers or GC with shortened Koni yellows?
Hi,
My car is DD and I will be autocrossing once a month or so. The roads I drive to work and school are pretty much average to smooth. I want to drop no lower than 1.5-1.6 inches. Moreover, my goal is to have a stiff and controllable (but not teeth jarring and kindey shaking) ride with good Handling and reliability.
After tons of reading and comparing prices I narrowed my choice down to these two. Cattman co's are $1,099 till Aug 10th while new konis + Ground Controls+new dustboots (old ones are pretty bad) will cost me about $1k plus extra installation time and some tools. By my understanding Cattman CO's does not have a damper adjustments while with GC/Koni I will be able to adjust the dampers. However, I could not find reviews on cattman CO's on 4th gen but I read some threads about GC/Koni setup.
So my question for people who actually used any of the above setup:
1. Do I lose suspension travel with Cattman Co's after lowering or the suspension travel will be independent from drop like other coilovers?
2. Are you happy with the Cattman CO's pre-set damper setting or is it too soft/ too stiff for you?
3. GC/Koni vs Cattman CO's -which one and why?
Please help. Any suggestions/conserns are welcome and I'm also open to
(of course reasonable ones lol). Thanks

The Progress' have shortened strut bodies so you will have good travel with a moderate drop. They're very comfortable for street so I'd think you'll want to order stiffer springs (default 8/6.25kg) and get the struts revalved. I would have no problem recommending these. In your case it sounds like the GC/Koni's would be right up your alley.

Default spring rates sounds fine to me and I'm sure that struts are valved perfectly for most people to be happy with. I still don't get it- why still I should go with GC/Koni setup. Sorry I'm a noob when it comes to suspension...
Another noob question-what is the "initial turn in response"? By my understanding it refers to how quickly car responds to steering inputs (like Buick or like BMW lol) or does it means something else?
I'm not sure if "initial turn in response" would be the same in both setups...
Anyone else with either setup please chime in and I will be happy to hear/read your comments/ concerns about it.
