come to think of it I might like the BBS wheels more than 5 spokes, but they almost look too good, like you notice the wheels more than the car.

I happen to like the RS-GT's in the black chrome And yes, they are not cheap but they are almost half the price of most of the 3 piece modulars or one piece forged wheels by Kinesis, Fikse or Champion.

I REALY like the Sport Techno's on the Cayenne and I'm growing a fondness for them on the Boxster. When I get my Pepper I might just have to get matching wheels

well if you go with an 18inch rim, you would put a 18X235/35 Front and the rear would be 18X265/30. i swear the 19z would be the exact same rubber, well in a 19 inch tire. so why would it be a harsher drive. i have 19inch rims with front
19X235/35 and rear 19X275/30. i would think that the car would drive exactly the same as a 18 inch rim or a 19 inch rim. if you plan to go aftermarket, it would be dumb to go with an 18inch rim. aftermarket rims....look for light weight yes, and 19z. if i had put 18z i would of been really pissed. 19z do not take away from the look of the car. it really isn't all that bling.

19z look amazing, makes the car look real mean not pretty.............

n if you want your car to look really good, make sure you get a rim with atleast a 2inch lip....looks really good.

What size wheel do you have on your car now? If they are 16 or 17" your gonna feel a huge loss of power when you put such a heavy wheel on the car.. Remember unsprung weight (wheels/tires/brakes, suspension) it's quite critical to have lightweight components on the car for best performance.

If you notice stock we have aluminum control arms etc.. Porsche did this to decrease unsprung weight at all costs, then you ruin it with 19's from Antera. It will be along the lines of a 10-20whp loss because of all the added rotating weight. Not a good idea.

Going from a 17" 29lbs wheel to a 15" 11.5lbs racing wheel on my GTI took about 3/10ths off the car int he 1/4 from 13.5 to 13.2. Thats a lot considering the car was already going mid 13's then to low 13's just from weight on the wheels. You could expect a full half to .75 seconds slower in the quarter and say 1 second slower 0-60.

Just a guesstimate of course, but it's not gonna be pretty either way.

well just to debate.....so you are saying that my stock 17 / 255 / 45 rear and 17 / 205 / 50 front would be faster then the car sitting on 19 / 275 / 30 rear and 19 / 235 / 35. lets just say that the rims were the exact same weight. i'm not sure that it would make a big difference.....unless i take the car to a track....which a boxster might not be my first choice of car to ruin on a track.....i would not suggest my set up for racing....but still pretty dam fast....raced a 350z and the car kept up, if not faster.......................

Kronix,

Check your tire sizes. Proper sizing is

225/40x18 - 265/35x18
225/35x19 - 265/30x18

Stick with those and you'll get the optimum performance. Your car isn't designed for super fat rubber. Besides, bigger = heavier and heavier = slower, both in a straight line and around a corner.

If you're going to customize then do it right. Don't turn the Boxster into a "Ricer"

The thing is you will never get the same weight to start, and secondly the inertia to turn a larger wheel even with a smaller tire of the same weight takes more power.

To get a 19" thats the same weight as a 17" would take Magnesium wheels which are about $5000 for a set, even then I dont think they could weigh what a normal aluminum 17" does really. Besides he is talking about buying antera's which are heavy ass wheels. You'll be adding 10lbs a corner easily over the stock setup. Thats gonna soak up a crap load of Hp.

So what about in my case? If I, with the optional 19" carrera classic wheels, raced and identical 987, only with the standard 17" wheels, they would out accelerate me?

Probably.......
