DTM is really good with installing kits.
Although when i had my front bumper replaced due to crashing in the canyons the body shop i used was called Brotman Auto Body in L.A./Monterey Park on Atlantic blvd. The front bumper pearl white matched PERFECTLY to the fenders. I can't remember the paint they used but you should give them a call and get a quote. I'll try to post a pic of the match tonight if theres enough light but tomorrow i'll have a pic up for sure.

Here's pics of the work i had done at Brotman.
