I'd ditch the tint all the way around...my 05 was tinted by the dealer as an add on and done very nicely. After about 6 years the rear window started to show some distorting or wavyness, so one day I stole the wifes steamer and went at it...30 minutes later I was de-tinted. As much as I liked the comfort aspect of having tint, the car just looks more suited to my 38 year old arse w/o it...lol. Brake wise I did 4/2 pots from a totaled 07 years ago...been pretty happy with them.
Looking forward to watching the build!
And hey if you need or have the want for a new cat back I have a g200 catback and injen sjs axle section that matches the invidia midpipe to go with it...shoot me a pm if interested.
