I had KW Sleeves and they worked well on the track when struts were new. However, if your struts are even showing slight signs of wear, the KW sleeves will exacerbate the issue immediately. You will get that squishy damper feeling especially on slightly bending fast straights - and that is not confidence inspiring. Also, at this point you'll feel the suspension tramp pretty harshly on normal streets, also something I did not like. Funny thing is, I'm thinking of putting on Eibach Pro Kits on the new M vs. Sleeves.
Are they becoming too soft for you and is the Eibach height not low enough? I see you have the Pro Kit.
