I saw a thread in the 99-03 TL forums about using an M3 trunk lip spoiler as well as the M3 roof spoiler on the 2nd gen TL. The trunk appears to be very similar in size, however obviously it's impossible to judge this based on pictures. Does anyone know if this applies to the second gen CL's? Additionally I would like to know which gen M3 spoilers they were discussing in the thread. Here is a link to the thread: https://acurazine.com/forums/second-...poiler-849463/

 

the M5 lip spoiler is slightly longer and fits the CL better. (the CL is slightly wider than the TL I believe). I believe this is the one people have used. (I have not fyi).
