SE struts may be better than LX struts, but nowhere near as good as the struts BAT has to offer or anywhere close to Konis. And I bet you paid an arm and a leg for 'em too from the dealer!

Check the BAT catalog and see how the prices compare

If you are looking for a close to stock looking suspension with better handling, then the BAT European Handling kit is for you.
