Fenders Rolled or Cut:
I had the fenders slightly rolled on Sunday just the rears no rubbing at all up front, over speed bumps at speed and hard corners the rears rub a bit...will look into pulling the rears.
Other Body modifications:
Rear strut clearance is 2mm no rubbing issues yet.
Tires: 255/40/17 Dunlop Direzza Sport Star Spec Z1
Suspension: Cusco Zero2R with 12k/10k springs
Alignment: -2.4 front / -1.75 rear
Fenders Rolled or Cut: NO, but I'm going to get it done.
Other Body modifications: None
Advice: Stiff spring rates are probably what's keeping me from rubbing the rear fenders. And if it is rubbing, I'm definitely not hearing it. I have yet to try it out on track to see if it rubs under harder-than-normal cornering.
I'm pretty sure T3h_Clap looks here from time to time, but just in case, many thanks to him for the many questions he had answered for me. I FINALLY went with a 9" wide wheel man, lol.
edit: This setup DOES rub on the track, and when going over huge bumps on the street/freeway. Other than that, it's fine.
265 would be what I would like to run. Maybe the next time around. the 255's look slightly stretched. Also, I may got with a different offset in the front since there is sooo much more room up front.
Wheels: Street - Buddy Club P1 Racing 17x7.5
Track - Rota DPT 17x9 et 42
Tires: Street - 245/40/17 Federal 595ss on the P1's
Track - 275/40/17 Toyo R888 on DPT's
Suspension: Hotbits DT2 with 10kg front and 8kg rear springs, strut tops set at maximum, camber bolts used to tip wheel away from strut
Alignment: -2 F/R, ride hight is around 14" F/R
Fenders Rolled or Cut: No
Other Body Modifications: had to remove Rally Armor flaps in front, 275's would rub the screws that held them on and the flap itself at 1/2 turn, there is a bulge/lip directly behind the tire in the front fender liners that had to be heated and pushed in for 275's to achieve full lock without rub
Advice/Notes: all following info is for 275's.. tires are 2mm away from front springs at the top of tire, for fronts to get more camber the tophats will need to be machined so the strut will tip in more, rears have lots of room to springs, trailing arms and the wheel well beside that gas tank/ where rear passengers sit area both have around 10mm or 1/2" of clearance, rear tires stick out of fenders by 1/2 " but i do not have the fender flares of the '05-'07 STi
Update: No rubbing whatsoever on the street. On the track had a couple of small ones. Launched the car sideways over a ripple strip. When it landed the rear tire touched the edge of the fender lip, left some thin rubber shaving on the edge of tire. I put my hand on the lip and it's quite sharp on top of the arch. Only happened once so the back is pretty good.
In one 2nd gear left / right hander (very aggressive transition) I had a very slight touch on the front. Haven't had a good look to see where.
Year of STi - 2005 Wheels: - 18x9 +45 Enkei PF01 Tires: - 255/35/18 Toyo R1R Suspension: KW Variant 3 w/RCE Camber Plates (F) Alignment: -1.5 front and rear Fenders Rolled or Cut: NOPE Other Body modifications: Nothing Advice: - if you plan on running this size wheel and tire combo, all you need is a good alignment with at least -1.5 in the rear, or under a load, the rear tires will rub.
