Schumacher True Cv Driveshaft
 

Has anyone tried these out?
I was thinking of trying them on a Cat K1 but wondered if they were worth the £45 price tag.

I have them on my K1.

The car absolutely feel much smoother when making turns. However, i am not sure if it would shorten your lap time:woot:

I ended up buying them.
What surface are you running them on?
I've only run them indoor but couldn't seem to tell the difference.

Indoor dirt
