Wheel Weight Differences
Hello S2kiers,
I am totally new to wheel weight. I've owned a civic that had rotas since I had never cared of being serious in the track.
Right now I'm selling a set of wheels that is basically not for s2k body (further modifications needed due to aggressive offset). I am thinking to get the Spoon CR93 staggered or the Enkei RPF1.
The following specs are:
Spoon CR93:
Enkei RPF1:
The RPF1 definitely weighs much less than the CR93.
My question is now, how disadvantageous is 4-6 lbs sounds to you guys in R&C section? The stock AP1 lacks of torque and if you add more wheel weight, it'll be more disastrous.
The s2k is my DD, but I'm planning to track with it 2-4 times next year.
Personally, I favor much more to the CR93s. The RPF1 is one of the over-used wheels, IMO.
Their price appear to be similar as well. Not only that but also the CR93s are discontinued.
Let me know what you think
Thanks

Spoon CR93:
- 17x8.5" weighs 19 lbs
- 17x9.5" weighs 21 lbs
Enkei RPF1:
- 17x9" weighs 15.65 lbs
The RPF1 definitely weighs much less than the CR93.

I have my doubts that in the hands of the average person reading this thread the same setup minus changes in wheels weights would result in any measurable lap time differences.

One thing to note: I'm not planning to achieve best lap time during track day.
Even for DD you'll notice the difference that your car becomes heavier if you upsize your wheel right?
Thats what I feel when I use 17x9.5 advan RS.

You shouldn't. 
Not exactly the same scenario as the one you're considering, but this is an informative read: http://www.caranddriver.com/features...d-tires-tested.

"Both drivers thought the lighter Enkei RPF1 wheels allowed the car to accelerate more briskly and work the slalom with more agility.
...
our Race Technology DL1 data acquisition system reveled that the Enkeis were slower.
...
the performance difference was rather insignificant -- less than a tenth of a second.

Close enough.

GRM figured this out a long time ago.
