im taking the TA to get the underside done, now my question is, is there anything else that could possibly get messed up besides the opti?...the reason the opti doesnt matter is cuz its getting changed out this weekend anyway, so if it dies more, big deal lol

 

bump...ttt

 

Nope not that I'm aware of.
I wash the undercarriage of mine quite abit (and engine occasionally). I just like my stuff clean.
