i am getting some kw varient 3's from robi next week and have to make a choice on spring rates.

the car is a daily driver but i am pretty involved in autocross, and will hit the track a few times this summer.

robi recomended 7k front 8k rear for daily driving but i dont care at all how stiff the suspension is, i dont mind having a stiff ride. he said that i could get 8k front 9 k rear if i didnt care about ride quality which is what i am thinking of doing.

the only thing is i dont want any body roll at all and i dont want to be stuck with too soft a spring by going with 7k 8k but how bad does the ride quality get from going to 8k 9k? thanks and any responses would be appreciated

 

You seem to have answered your own question. You said you don't care how stiff it is, so get the stiffer rates. Are those the max rates that Robi recommended for the KWs? Those are still on the soft side for coilovers, particularly if the application has no regard for ride quality. Vishnu Ohlins for example go up to something like 12k/16k. Maybe if you want to have the sort of rates usually used in track applications you need to go with the $2800 KW Clubsports?

 

I've had 8k/9k on for about two weeks now and it seems fine if you set the rebound and bump up for street. If you plan to be competitive in autocross, I suggest going with the 8/9.

 

thats also something i was wondering.....i think he said that the 8k/9k wont be too bad for the strut on the street setup or something like that he was saying......

maybe he'll come on here and clear it up!
