I have them on my RX8. Previous set up I had was Koni yellow sports adjustible shocks and eibach springs. So comparing the racing logics to that set up..... a lot more responsive, slightly more bumpy however..
I do have pretty high spring rates, not sure exactly, i can find out tho.. They mainly set up for my track events.. I dont have them on very tight atm for daily driving, so its still decent ride. It can just get a bit annoying when the roads a bit crappy, but the price u pay for decent suspension!
Dont know what you mean by 'you get what you pay for' sure they dont cost as much as teins or something, but all depends what you want from the coilovers. If you are after something better then stock, but not necessarily wanting to spend a fortune, i think they are decent. But if ur going to be out on the track often and thats your thing.. well thats when you invest in something a tad better
If u want to c photos let me know and i can post some....
