Hey guys, just lowered my car and I'm looking into getting some apex ec-7. Going with 18's. 9.5 in the back with a 265, unsure if I should get 8.5 or 9? Planning to stay low so I don't want any rubbing issues. What size tire and wheel width would be good? Also would 8.5 or 9 be better for handling?

best handling is square or stagger that is near square, i.e. 245/255 255/265
from the widths and offsets available for ec-7, your drop and a N20 engine (which is not that mighty) i'd do 18x8.5 ET35 face1 with 245/40 front, 18x9 ET31 face2 with 255/40 rear if you're set on having 265 rear then 18x9 ET31 face 2 with 255/40 front and 18x9.5 ET35 face2 with 265/40 rear if you don't mind a bit of understeer then 18x8.5 ET35 face1 with 235/45 fronts and 18x9.5 ET35 face 2 with 265/40 rears. you could do 245/40 fronts also but your car will sit lower in front by 9/16" (forward rake) since your lowered a lot, if your fenderwell gap is none or your fender is below your tire you may rub with any of these options and may have to adjust your coilover height or adjust your camber |

you'll have to load each corner and adjust camber accordingly, until it doesn't touch. if you add camber it increases the handling albeit at the expense of inside tire wear. here's some race camber pics |

Really like that the performance would be great, but just not a fan of the look and stance of the car. I like the look of these cars, and their fitment is amazing imo. If I were to go this route, what size tires would I need? Also would I need spacers? And what size wheels would be suitable to look like the following pics but in 18's? Thanks for your help really appreciate all of the knowledge. And one other thing, would I have to roll or pull the fenders to achieve the fitment of the white f30? And are those 19's on it?

the cars in the pics are running stretched tires so that the sidewall is going inwards thus giving more clearance. i'm not a fan of this and it will cause the car to handle more poorly because the sidewall is part of the tread during hard cornering. you could do mild stretch by downsizing 10mm from optimum tire width for a given rim width. the rear fenders have nothing to roll. the fronts could be rolled however i'd refrain from that unless that's a last resort. it's easy to damage/stretch the metal and crack paint unless you really know what you're doing. i notice both cars are at least 19's if not 20's and have deep lips which an 18" ec-7 looks nothing like. you may want to change your selection to 19's and a different style Last edited by alohasurftoad; 05-27-2016 at 01:09 AM.. |

here's some info.
http://www.myapexparts.com/2013/08/0...ly-aggressive/ maybe run a similar setup except 18x9 ET31 Face2 with 235/45 Front (so there's no rub) and 18x10 ET33 Face2 with 255/40 Rear. so the stretched part of the sidewall will tuck. sorry change the rears to 18x10 ET43 Face2 with 255/40 check out this thread and notice wheel widths, tire widths, offsets etc and try to figure out from there. http://f30.bimmerpost.com/forums/sho...d.php?t=909786 you don't need spacers as the wheel lip will already be outside of your fender. you may also need front camber plates, not sure what they use to increase rear camber adjustment if the stock adjustment is not enough. i suggest asking apex specialist since i believe in functionality and performance over form/looks. i don't believe in tire stretch and having extra rim material to create that type of look as it's just added weight, less protection and compromising the sidewall if the stretch is too extreme and your cornering hard if your going with the modular i'd say just copy the widths offsets and tire widths listed in your other thread. you don't need spacers since the offsets are low and your rim is wide Last edited by alohasurftoad; 05-27-2016 at 10:49 AM.. |

Thanks for the help. One last thing and I'll stop bugging you. What do you think of a square setup of 9's all around with 245's. Or 245 in the front and 255 in the back. Would this look good and sit flush? And maintain the same ride height with 18's? Thinking this may be the best route. What offset should I run all around? And what tires 245/40 or 245/35

if you do get ec-7's the size you should get is 18x9 ET42 front with 245/40 (or maybe 235/45) and 18x9.5 ET43 rear with 255/40.
http://f30.bimmerpost.com/forums/sho...pex+18x9+%2B42 if you notice M-Terkait's blue 335i has these sizes and it appears that it is flush with non stretched tires. if his was lowered to your height, it would rub. since you would run mild stretch it would help but i'm not certain it would not rub. |

definitely query whomever you're buying the wheels from about all of this. don't take my answers, suggestions, opinions as gospel. i'm definitely not responible if something doesn't work out. just trying to help would be nice if some of the "stance" guys chimed in additionally M-Terkait's car appears stock suspension. not sure how close the inside of the front wheel will be to your KWV2's.

it says 19x8.5 ET35 front and 19x9.5 ET40 rear. the tire size looks like 245/35(or30) fronts and 255/35(or30) or 265/35(or30) rears. contact VMR for exact answer |

F: 235/35R19 w/ 19X8.5 +35 (+12mm spacer, so effective offset is +23) R: 265/30R19 w/ 19X9.5 +30 and lowered to where i can barely clear a folded newspaper laying on the ground, and i have no issues. However, i have little room for margin. I could probably get away with an additional few mm in the front, but the rears are perfectly fitted to provide the lowest offset possible. There may even be a few millimeters of poke in the rears. I can post a pic if you want. I was using a 275/30/19 w/ 19x9.5 +35 on the rears with the old wheels, but with the additional 5mm offset decrease with my new setup, i had to go down to 265 to insure it was going to clear. i might have even gone 255 or lower to do a stretch (so that i could afford a little more poke), but in the end i like the look of a beefier tire on my setups. However, with all that said, i have no rubbing issues on the wheels. About the only thing that scrapes is my splitter lip going over steep driveways and extra large speed bumps, but i make it over safely over just about everything else. But the wheel/tire set up is giving me NO problems with the fenders, rubbing, etc... Of course, i have to dial in the ride/coilovers to be stiffer, as with a set up like this you don't want to be bouncing around going over bumps |

Joe -
If my setup will work with no rubbing, yours is a slam dunk. I would recommend you read this article by Turner so that you have a better understanding of offsets work: https://www.turnermotorsport.com/t-wheel_guide As to your spacer question, it really depends on how aggressive you want your set up to look. In your pic, its very clear that the tires are sunken into the wheel well a good 1/2 inch or more. To me personally, because i like a real aggressive look, i would push those suckers out till you are at least flush with the fender. The first pic below is my car with 19x8.5 +35 with an added 12mm spacer. You can see if you like that look. So without it, the tire would be half an inch more sunken into the well. I don't have any rubbing issues. Also, for reference, you can see the newspaper laying on the driveway so that you can see how much my car is lowered. Btw.. if that is a pic of your car, i'm way more lowered than you, so again, you shouldn't have ANY problems what so ever. As to the rears, my offset in the back is +30, which is a little bit poked out past the fender, but only by a few mm. Flush would be just over +35. Since you are at +45, you are waaaaayyyyy safe. If i'm lowered more than you and have way more aggressive offsets than you, and i still don't rub, then you have nothing to worry about. The only thing i would worry about if i were you is if people look at your car, and go "meh, he could go more... " Last edited by squidlyboy; 05-30-2016 at 02:33 PM.. |
