Ive been dealing exclusively with Brenspeed for my new 2013 as far as performance parts is concerned...Mostly I Deal with a guy named Miles and ive got to say the Brenspeed team has the best customer service i beleive ive ever encountered in my lifetime of dealing with speed shops....they are extremely knowledgable, they sell great products,have amazing prices and lightning fast shipping...Im in Toronto Canada and my orders usually get to my door in 72hrs...Their tuning department has my new auto 2013 GT going 11.58 @ 119.65 best to date and thats with basic weight reduction(mostly free) their 93A tune,full exhaust,410 gears and racestars...ive never put the car on the rollers to check rwhp or tq or even a/f ratios but the car runs and drives like a champ and i just wanted to comment on my Fantastic experience with Brenspeed...Thanks Miles and the Brenspeed Team for making my modding experience enjoyable!
