Gary,
With the 18 & 17" wheels I could have gone larger and would have made the bracket easier to make ... there was conflict with the bolts with the 12" rotors. I have an extra set of brackets if you need them.
I would like a set of lighter uprigths ? whats the cost ?
Ron
Thanks Ron, I am not sure what else I will change. I can have my neighbor laser cut them and get them back faster then you can ship them. Did you notice mine were generation 1 uprights?
The brakes and calipers made a huge difference in weight and was all unsprung. Did you weigh the difference. I have not yet but the old set is far heavier to carry around then the new set.
I think the aluminum up rights is the obvious way to go. As much improvement there is in the brakes and calipers, I move the rear upright assembly around with a 2-wheeler and that just ain't right. It doesn't take a rocket scientist to figure out where the weight is.
I may change the a-arms for other reasons but more for geometry reasons. I don't care to spend time to lighten weight from the a-arm or axle as it does not have near the effect of the rear upright, brakes, calipers, and rims with proper back spacing (removing spacer).
But that's just me. If I am last one going around the track I don't think you will notice a change with a-arms or other items with 1/2 unsprung weight.
