Not sure how they compare since I've never seen the SPL's first hand. I know that TC uses very good bearings and builds very high end race cars. Yes he's got front and rear. They've been on my car for a couple of weeks now.

 

Still not seeing the endlinks listed on their website. How much for a front pair, and how much for a rear pair?

I asked the other question b/c I had heard they were the same as the SPL ones, as if one was a rebranded version of the other?

 

TC's are $300 for the complete set. I can assure you that they are not rebadged parts. I personally saw him put a block of metal in his CNC machine and make the cone shaped washers. Very cool machine.
I don't think the Z parts will be advertised on his website since most of them are one-off parts. Best bet is to give them a call. It's good that we now have some more options for the Z.
