Weight of wheel

[JayG]

I'm looking at picking up a set of Racing Dynamics wheels as a spare set for track/AX use at really good price.

From what I can tell, they weigh around 6-8 lbs more that the Boxster S wheel I use now.

I know heaver wheels can effect performance, but in reality how much? My car is basically stock, soon to get a suspension upgrade with coilovers. I am a relatively new track driver, about 18 track days under my belt. I am not concerned with a few 10'ths in lap time, but several seconds would be a concern

My thought is to most likely use them for practice sessions on the track and switch to my lighter wheels for timed runs. Maybe the same for AX.That way I can save my "good" tires for when it counts. Or, since the new wheels would let me use wider tires on the front (8" vs 7" wheel, use them for my timed runs

They also come with with 4 virtually new tires, but not ones I would use for the track or AX

My AX wheels are about that much lighter than my street wheels and I notice the difference in acceleration from slow speeds and a bit in braking. It's not a huge difference, the car just feels not as immediate with the heavier wheels.

my summer set wheel+tire weight is 46 lbs. Winter set is 55. What a drag. Unless you have 400/500+ lbs of torque, wheel weight makes a decent difference. My new tires for summer should weight less than the ones i currently have and should be closer to 42lbs which should make it easier to get going

I picked up the wheels and to my surprise they are only 1-2 lbs heavier than my Boxster S wheels!
