Rotating mass is the best place to save weight. Although with a wheel it may seem like you're only saving, say, 4 lbs per corner, think of how much energy it takes to spin an extra 16 lbs when you're at a standstill. It's an easy way to enhance performance, provided you don't get crazy and put on a heavier 245/285 tire combo that will help with lap times but not acceleration.
Yes, Fikse and Kinesis are strong and light wheels.

Richard- These wheels are 10.5 x 18 which may be why Kinesis moved offset inward by 1/2 inch. On Tuesday I will call Alan at Kinesis to be absolutely sure that the 60mm written on the receipt is the way the wheel was built---since there is a serial # on back of each wheel. No, I did not use spacers and the fitment with 295 rear was perfect.

So weight and strength usualy take priority over appearance, then it gets down to how flush I'm feeling at the moment I need to pul the trigger and buy the wheels.

Umm... there's a reason I asked why.
Let's say you're saving 4 lbs of sprung weight for every 1 of unsprung weight. So, fo every 4 lbs per wheel (fairly huge, btw) you're saving a whoopping 16 lbs of weight. Or 64 lbs on a 3100 lb car.
No, I race a 2300 lb car that currently has 9 lb wheels (actually, 8.8, but we woudn't go there). From personal experience of racing the same car with 13 lb wheels, and we're talking much hihger ratio to total weight here, I can tell you that the difference is hardly perceptible.
In other words, I do not understand this Honda-induced craze for light wheels at any cost. None of the cast BBS wheels are particualry light, and I'd take those any day over pretty much anything else on the market. Same for Kinesis, HRE and a few others.
I can understand light wheels for the track, where every pound counts and the surface is smooth and you can afford to throw away bent wheels after every race if need be. I perfectly agree with what Mark says (look very carefully at his car and understand its intended use). But for a street car with occasional track day? To pay much more for a lighter wheel only on the metir of weight and theoretical advantages? No, I would not.

If you have wheels which weigh 4 lb. less per corner then your 3060 lb car weighs 3044 lb. which your car still has to push forward. It would not seem to make that much of a diff. in acceleration since the driven wheels still have to accelerate the entire mass. However, unsprung weight is another issue.

And exactly how far did the car go on the dyno? The wheels are driving the dyno not the car. The dyno is also one of those places where hp gains may be observed from a LWF.

So what are the offsets of the wheels? If the rears are indeed 60mm offset, wouldn't it fit a narrow body? Also, do you have any pictures of the wheels on your car? I'm so tempted to take these off your hands.
