what would i have to do to get new wheels on my 09 audi a4 2.0t premium plus model .. i wanna get 19 x 8.5 wheels and right now i have the stock 17s on it.. i cant make up my mind on which wheels i want to get.. but im pretty sure i want 19 x 8.5.. maybe these? http://www.finishlinewheels.com/spec...28Set+of+4%29/ ... what would i have to do to get new wheels on and lower it with eibach springs.. would that mess up the cars computer system? i dont really know how it works.. or would they rub? or mess up the turning? 19's and lowered.. let me know what you think and if you have any other cool wheels that you think would look good on my car let me know.. because i cant make up my mind i got like around 1000 dollar budget for wheels.. but wish i could get some hre's haha

 

Have you ever driven a car with 19's? They look bad *** but if your wife or anybody else drives that car without being careful you WILL be buying new wheels and tires AGAIN. Go with 18's and get a set of tires to go with them. http://www.oewheelsllc.com/Audi-Whee...-p5939296.html These are cheaper than the ones you linked. You could get these powder coated to match your paint?!?
Put 1 of the mounted 17's in the trunk (hopefully it will fit) that way when the lease is done you can throw the 17 back on. I'm not familiar with putting Eibach springs on but the main reason tires rub is not so much from lowering the car as it is from the offset of the wheels. Talk to the spring mfg about how it could effect the cars electronics.

 

im thinking about vmr v710 wheels.. 19 x 8.5 in gunmetal my car is quartz grey so i think it would look perfect.. heres a link http://www.audizine.com/forum/showthread.php?t=243846 .. you think its that bad driving 19's?

 

Gotta say those wheels look sharp...nice choice. You will probably end up running a 235/35-19 which will tighten up the ride a fair amount and make the car more responsive. Pot holes and speed bumps will not be your friend. Don't get me wrong 19's are NOT a stupid idea. You just need to be paying attention 24/7...the little bumps that used to be no big deal (like turning to tight into a driveway because a SUV is leaving you to little room for a wider turn in) can sometimes say "Gotcha" and bend a rim or pinch a tire and give you a flat. Don't be afraid just be aware. I had 18's on my Subaru STI w/225/40-18 and didn't have much problem. The wife has 18x7.5 on a '03 Mazda6 with 215/40-18 and bent 1 rim, we replaced it and she has another that has a bend in the outer lip but it doesn't leak so it still is on the car.
Get the 19's and be carefull that's all.

 

How do rims affect performance? My friend is obsessed with his GTO's weight Nd says that rims can slow the cAr. (he even took out his back seat Nd removed some stuff under the hood.

 

The simple answer is (all things being equal) that the lighter a car is the faster it will accelerate, the faster it will stop and the better it will handle. Lighter wheels reduce unsprung weight which improves handling. Imagine the difference between holding a 5 lb weight and a 10 lb weight in each hand with your arm outstreched. Which arm will be easier to control? Well that's easy, the one with the 5lb weight. If you apply that same theory to your cars wheels you can see what your friend is talking about.
It's more complicated than that because larger diameter wheels allow you to run lower profile tires (that usually are WIDER as well and wider tires can give
you better handling and braking!) without changing your speedometer. (Same OVERALL diameter as the original tire.)
BUT there are trade offs between tire and wheel width VS weight.

 

Big wheels and tires will give you more grip but they tend to slow the car down a little as well. Weight is the enemy of acceleration but wheel/tire weight much more so. Your cars power has to stop and start the weight of the car in a straight line. With wheels/tires they have to accelerate in a straight line and in a rotational direction. A nice set of super light forged wheels can negate this effect but will run you several thousand dollars.
