Not necessarily true. True, steering feel will be better with the +45, though not necessarily be better in terms of handling. If anything, a slightly wider track would promote slightly higher grip and stability, just at the cost of decreased steering feel and precision.

If i'm being honest: #1 and #2 are MPG and Looks (Tied) #3. Weight #4. Performance (In terms of cornering) I don't autocross, my WRX is a DD commuter that I like to look good in 99% of the time. The other 1% is Snow Trips which I have winter wheels and tires for. |

I ran 18x8.5 +48 SSR GT2s with 255s, 17x9 +42 DPTs with 255s, and 17x10 +38 RPF1s with 255s. The SSR GT2s weighed 18lbs, the DPT weighs 19lbs, my RPF1s weigh 17lbs, stock BBS (17x7.5) weigh 16lbs, and the stock BBS (17x8) weigh 19lbs. You are greatly exaggerating how much performance suffered because I could barely notice any difference at all between the 5 different wheels. What I did notice is a huge increase in grip thanks to 30mm of tire. That, or you have the most sensitive buttdyno ever. |

Pardon me sirs but I have another question. What would be the ideal offset for 17x8 with stock suspension to have the wheels close to being flush and not have any rubbing/fender modification. Thank you.

Hey guys I'm picking up a set of evo bbs wheels.
They are 8.5 with an offset of +38. Will I need to do any fender rolling if I want to run rce yellows? They drop the car between 10-15mm. Also what tire size do you recommend? I was thinking about ordering a set of DWs in 255/35/18 |

Choose different all-seasons and go with the OEM 245/40/18. Not sure why you would want a wider all-season. |

Cool thanks! I've taken about 20 measurements and it looks like they may clear but it would be really close so I will play it safe
Just curious why should I not step up to a 255? Is it to wide for an 8.5 rim? |

I'd say a 255/35 will actually have less chance of fender rubbing than a 245/40 as well, because the diameter is almost three quarters of an inch lower, so the extra 5 mm the wheel will poke out wouldn't be as big a deal, and plus you're also running wider tire then, which means more grip |

Thanks again for the response. I've been reading for hours and it sounds like I am going to run the DW in a 255/40. These aren't for tracking I've got an extra set for that and I didn't want to step down to a 35 because the extra meat should be more commute friendly for me.
Thanks again for all the help, I can't wait to get these mounted up! |

255/35/18 will be easier to fit but I like the gearing advantage of the 245/40/18. |

What do you guys think about 18x10et38
On a 2011 WRX Rolling is a given , what about clearance on the inside? You think it'll rub anything? Coils? ** I'm on coilovers |

EDIT** i agree wider tracks are USUALLY better, but this is not always true. there are always exceptions to the rule, and more factors that come into play. suspension works as a system of all components designed to work together. if you change one thing it will effect how the rest of the system behaves. I think however, that for the purpose of this discussion these other factors are not entirely relevant or appreciated Last edited by 07VTRex; 03-04-2013 at 12:56 PM. |

17x7.5 BBS (16 lbs) + 225/45/17 RE070 (27 lbs) = 43 lbs 18x8.5 SSR GT2 (18 lbs) + 255/35/18 KDW2 (26 lbs) = 44 lbs 17x9 DPT (19 lbs) + 255/40/17 RE01R (27 lbs) = 45 lbs '03 STi 17x9 FN01RC (19 lbs) + 245/45/17 Star Specs (28 lbs) = 47 lbs 17x10 RPF1 (17 lbs) + 255/40/17 R1R (25 lbs) = 42 lbs 18x9 RC-T4 (20 lbs) + 245/40/18 SP600 (26 lbs) = 46 lbs That's the order I've gone in not including winter setups. The difference was only 2 lbs per corner. Maybe it's the 1 lb increments but I hardly noticed a difference at all on the '04 STi. Then again, I don't focus on acceleration as much as I do going around turns. On my current car, I did notice a difference. Felt like I was carrying a passenger but I don't pay much attention to the difference in weight. However, this isn't pertinent to the thread so let's take it elsewhere. Did you bother searching? If you're too lazy, use this http://www.1010tires.com/WheelOffsetCalculator.asp to calculate the difference between the what is known not to run on the inside versus what you're looking at.

dude this is a great write up,i have 2012 wrx sedan and i want to fit a set of rota grids 19" 9.5 ET 45,but the mech told me that the 9.5 is to wide and will touch the suspension? yet you have just said that from experience it doesn't and the range of offset is 53-45,the reason i want to go with the 9.5 is because the 9.5 has a deep concave look as compared to the 8.5,i'm not planning to lower the car at the moment but will in the future,i also don't want to do any fender rolling now as the car is still under warranty and brand new,i really like these rims so your advice will really help me decide.thanks

EDIT: he also blatantly said that if you want no rolling you'll need a higher offset with a smaller wheel/tire... 19" wheel, 9.5" wide and you are set on not rolling your fenders? Think you better set yourself on a different set of wheels haha |

Step 2 - If you don't want to roll find new wheels that are no wider than 8.5" Assuming you really want to run these wheel take a look at the following To keep the rolling diameter within the 2% rule, You will need to run a 265/30R19 which puts you within .2% of the rolling diameter. You aren't fitting a 265/30R19 with a 19x9.5" wheel without rolling. Stock suspension or not. Some Facts: The wheel/tire is 7 mm (0.3'') closer to suspension/brakes components. Acceptable for most cars, but you will need to measure. The wheel/tire will stick out 23 mm (0.9'') farther. Basically will stick out an inch further which basically necessitates a roll. Think about your decision go do some measuring and do your homework and decide if you are ready to make the commitment to modify. |

Okay. I can already see this coming off wrong, but I'm looking to get as much width as I can. I like the fact that I can interchange the wheels between my EVO [yeah, I own one, start stoning me now if you want] just so I don't look at the same wheels all the time. I know 18x10 will fit on my EVO just fine with a roll and just seeing if it is the same case on the STI. I did tons of reading, research, and asking questions and 18x10 seems like a gray area - no one wants to touch that.
So, this is my question. I'd like to put 18x10s on the car but be able to turn and not rub to oblivion. I don't mind rolling the rears and even pulling VERY slightly [not about to go get body work to fit nice, wide wheels]. If I did end up going 18x10, what offset will I need to both clear my Brembos, not hit the struts in the rear, and fit with very little modification? I know I can go 18x9.5 without an issue so I figured I'd give this a shot. The car will be lowered on either KSport or BC's - whichever will achieve good ride quality and still get me low to the ground. If this isn't your flavor, please just ignore this post and stop reading. If you want to help, I appreciate it greatly. I really like the Work Emotion CR Kiwami and Enkei NT-03's. I wanted Emotion XD9's but after seeing how many people use them, I decided I want something nice and concave or something with a decent lip that isn't the price of a vacation to the Bahamas. Any and all help will be appreciated. Any and all flaming will be ignored. |
