Matt’s OG 2004 STi

2004 Subaru Impreza WRX STi done right. Matt has been in this game for along time, Matt has had his Subaru Impreza WRX STi for over 7 years now. The list of guys who bought their 04’s new and still have them and still modify them is slim. Matt is currently on his 4th wheel/tire/suspension combo.  With only 31k miles on Matt’s Subaru you probably guessed it isn’t his daily driver. It’s one of the lower mileage 04 STi’s I’ve come across in quiet awhile.
Matt’s car gets to see some track duty so you’ll notice he likes his R-Comp tires, between the Yokohama Advan A048 and the Toyo R888 he’s used to having some extra grip. This Subaru Impreza WRX STi has grown, from the stock 17×7.5s to some 18×8 Enkei RPF1s then some 17×8.5 Advan RGs (original RGs) and lastly some 18×9.5 +40mm Enkei NT03+M in SBC. To get the 18×9.5 +40mm Enkei NT03+M to fit his car Matt needed 10mm spacers up front (to clear the brakes), some fender work, and some tweaking of his Zeal Function v6 coilovers.
