Recently I think I've had an important question answered: If possible, is it worthwhile to put S springs in a Cooper? The answer is yes. I'd gotten a free set from a good bloke and had Detroit Tuned put them in for $80. And it has made a notable difference. I know it's a good thing to step up to even more capable springs if you're going through with gutting the old ones, but the S springs (and S sway bar - thanks, mates!) have made cloverleafs an even greater joy.

 

Kowalski? Hows the White Challenger doing?

 

I got S springs, bars, and struts in my cooper
