Agreed and derogatory comments are unnecessary (opinions are entirely different). 20s can look very nice on a GP. Also 20s by themselves do not raise up your car at all. It depends on the tires you choose to go with them. Now if you put large enough wheels on your car then yes it will without option.
As others have stated I would upgrade your overall brake system.
Depending on the weight of them it may also be harder on the trans than stock. Most things are. LOL.
The key in my opinion on 20s is to keep them classic and clean. I personally wouldn't go over 19s on my 99 GTP (18s is the largest I ever actually have). My Comp G maybe, but way too many things rank higher in my mod list.
I have to agree and disagree with you a little bit here Lowlyfe. I agree the comments are not needed. Personally, I don't think 20's belong on our cars. Trucks, SUVs, even bigger FULL SIZE passanger cars are ok ie the Charger/300 etc. This craze for 20s started in certain circles, just watch MTV, nuff said there
As for the height thing. I just put on my full set of 18" TSW Mondellos and I could tell a diffent difference in height. I can only imagine going from my stock "winter rims" to a 20" rim would be quite noticeable.
If you look at this picture when I was sampling how my 18's would look on one side, you can see how the car listing. The rubber on the TSW's is 245/45/18 while on the passanger side its the stock 16" rims with 225/55/16 Goodyear RA's. The lean is noticeable.
Everyone is going to have their opinion on the size of rims they want, like you, I would never go past 19. For me 18's are just the right size for our car, plus when you get into those bigger size of rubber the cost of your times is gonna jump pretty high.
The affects upon the tranny I would say would be more cause of the fact the engine has to push more to drive the bigger diameter wheel and thusly affecting the tranny. And like Steven said, it will chew up brakes alot faster cause there is so much more force stop as compared to a smaller rim size.
I guess the best thing is to let whomever decide what they want, and they will have to figure out, good or bad, about their choice. We can just give them good information without to much slammin' of their choice
