So after weeks of sitting with a design team here in Dubai I've finally signed off on a custom design with work scheduled to begin September 17th 2011 and to be finished by September 27th.

The mods will include a new molded front bumper with integrated LED's, a rear diffuser with the porsche/lambo style tunnel intake, various detailing.

Now after weeks of searching for suitable aftermarket rims I've settled on Incurve IC-S5's


I am however a complete novice at this and despite trying to research and understand how wheel sizing, spacing and offsets work I am still at a complete loss.

I'm hoping you fine gents can help me out a bit:

* I do NOT intend to lower the car at all.
* Current wheels are stock 2011 Sport wheels (114.3x5, 19x8.5 19.9)
* These new Incurve wheels will be 114.3x5, 20x9 20x10.5

As I said I will not be lowering the car at all so I want to know a couple of things:

a) What tyres do I need? I hear Sumitomo are a good brand for this region but what about sizing?
b) I understand that the offsets are +25 for these wheels, will this cause an issue?
c) What do I need to know about using offsets with larger wheels? Does it deter from handling? Does it affect the wheels/tyres in any way?
d) Will there be any friction or problems by using this modded setup?
e) What do I need to look for to make sure everything is put together properly?
f) What happens when the dealership services the car and takes the wheels off the check the brakes or otherwise?

The reason I ask is because everyone is grossely incompetent here and you basically learn the hard way that you really need to scrutinise and know everything about what you're doing or you'll end up paying for it later.

Thanks alot for your help

 

those rims are nice and I hope you receive all the help here gl!

 

If you don't lower it and have 20s, you'll look ridiculous.

 

this^^^^

 

honestly, if your going thru all this work to get a custom body kit and new wheels, lowering your car is a MUST. even if it is just the eibach pro kit. It gets rid of some wheel gap but wont interfere with the drive-ability

 

please at least get the prokit!

 

Thank you for your input but I respectfully disagree. I think these cars look absurd when lowered particularly to the point of where the wheels start to cave inwards like they do on some of the cars members here have posted. Talk about Car-bage.

Either way this post was not about opinions on lowering. I need answers to the questions I asked.

 

With all the work you're doing, you really should at least just get rid of the 4x4 wheel gap, it's a must. At least the Eibach ProKit, just lowers your car by an inch but trust me, it makes a difference.

245's and 275's should be fine

+25 for both fronts and rears?
Your fronts will fit nice, rear will poke out a bit. You'll need a little negative camber and drop to fit them. Try and see if they have offsets in the high 30's for 10.5" if you don't plan on dropping your car.

Nope, wheel width and offset only tells you how much they'll tuck in or stick out.

You rear wheels may rub on dips/imperfections on the roads

Well I'd make sure you don't get your tires mounted at a ghetto shop because they will scratch your wheels. As for the custom bodywork, if they're as good as you say they are then I wouldn't worry much there

It shouldn't be a problem unless they want to be a**holes, my car doesn't clear their jacks so they stopped admitting it in but that's not the case with you I believe.

 

Why do you have apicutre of a lowered car? Just curious. I wish I could answer you other questions but I can't. I will tell you I stand behind your decision NOT to lower your car. I think they look fantastic the way they are.

 

I hate that look.....but I still must disagree. This is me on eibachs (the car in the front). I'm higher than most and higher than what I was on coilovers. On 19s. Doesn't look "absurd" at all

 

I know you are getting a lot of flame for not wanting to lower your car. However, the picture of the car in your original post, which I assume your are modeling yours after, is significantly lowered. I, like most others here agree, believe that wheels are only half the look, and that it is important to have a proper lowering kit to achieve the desired stance. Without a lowering kit of some sort your car, though it may have the same wheels, will not look as attractive as the one pictured above.

best of luck, and happy modding

 

to each their own...
remember that lowering the car is not just for looks but for handling as well

i think that you'll hear from alot of ppl that you need to lower the car. even if you had stock wheels. it makes a huuuuuuuuuuge difference.

take a look at some of the guys here in the gallery and decide for yourself.

i'm lowered but not SLAMMED

good luck either way

 

I don't actually think the car looks good in the picture I posted. I was posting the picture only to illustrate the wheels I've decided to go for in an attempt to ensure whoever was reading the post fully understood what wheels I was going for.

Call me stupid because I really don't understand this stuff but to me it seems quite simple. Increasing the wheel size and thus its dimensions should bring the wheel closer to the body by 1 inch anyway shouldn't it?

Btw something else i forgot to ask - if I swap out wheels and tyres will I need to have new sensors installed for tyre pressure etc?

 

^ You can either swap over your existing TPMS or buy new ones and keep the old ones in your stocks

 

If you went with a higher sidewall on your tyres yes, but then your car would sit higher also and counter that effect some. The reason people say it will look bad is because the overall height of your car will raise also.

A conservative drop is something that you don't appreciate until you do it. One thing that really stands out to me is wheel gap. It really is ugly once you can appreciate a lowered car. Every month or so there is a member that feels the same way as you do, and he or she gets the same debate going. It certainly is your decision on what to do with your car, but you can't get upset when you ask for help and claim to not know what you are doing.
