This customer came in with a 997 Turbo pushing around 700 HP. He told us the car felt sluggish at lower speeds and we thought one noticeable difference from this car to the next was the 20-inch wheels he was running. Just driving the car around our parking lot, it felt anchored (as if the hand brake was engaged). It's a tiptronic, and when putting it into reverse from a stop, you would also notice the car creeps back much slower than a typical tiptronic turbo.

He was looking for lighter wheels, so we recommended the HRE Monoblock P40 19-inch in this case.

Here are some pictures of the car with the 20-inch wheels:



Pulling these wheels off the car I think I strained my back. :)



Weighing the rear:


And the front:


The HRE P40 rear:


Here are the P40 fronts:


68 vs 55.5 = 12.5 pounds saved per rear wheel
60 vs 45 = 15 pounds saved per front wheel
A total of 55 lbs removed from the car's wheel weight with one change, a savings of unsprung weight and more importantly for acceleration, rotating mass.

* Keep in mind he also changed to 19-inch tires, but the same size and type. This would be necessary for any wheel size change but the weight is reflected in the tires too.



And hey, it doesn't look bad either. ;)

Too big wheels aren't good. When I see all the pics of 458 on 21" wheels I could throw up!
I'm glad you could convince the owner of 19" wheels!

btw. Does that car really has stock brakes? Aren't those a bit tiny for 700hp?
