Hi guys I'm new to Acurazine.
I was able to find a rear aspec under spoiler and I was just wondering if anyone has ever put it on there base TL?

 

If you're speaking of the Type-S rear a-spec under spoiler, yes there are many that have put it on their base TL

 

i installed a base aspec rear on my 05 myself.. first time installing it myself, took about 3-4 hours and requires a drill as you will be drilling into your oem bumper.. i went super slow went over each step to make sure i did everything right and it came out perfect
i would say difficulty level would be about a 4 or 5 out of 10.. drilling into the bumper was the most nerve wrecking but everything is pre-marked to make sure everything goes smooth
