i have an '09 335 xdrive coupe. the ride height, imo, affects the overall look of the xdrive noticeably. I want to put a bilstein/h&r set-up, but the reason why i went with a new car this time is for the warranty advantages.
so after reading the above, i have to ask for your opinions; if i were to replace my current "xi" springs with "i" sport package springs, do you think the mod would fly under the radar with the dealer.... Also, it is important to know that it is a certified pre-owned, and the car could have very well have been modified by the previous owner... and since it was replaced with oem, it wasnt caught before...
Also, can anyone who has done the after market swap let me know on the dealership's reaction and/or any horror stories?
