Sparta GP-1 Slotted Rotor Experiences?

dmdodd83 · 01-25-2019, 03:09 PM

Hey there, first post (of many I'm sure

)

I've seriously been searching all over the forums and the internet to find examples of the Sparta GP-1s (their intro low-cost 1-piece design) installed on any car really, but especially e9x and even better would be seeing the 348x30 on a 335i. But alas, zero pics I could find.

I suppose I could look at their BBKs and in-my-mind scale the rotor down size slightly, but would love to hear some reviews and see some pics if folks have been running the GP-1s.
Also, are they directional, as in you get one (1) "left" and one (1) "right" (so the slots are both pointing in the same direction)?

If not, since the ECS 2-piece rotors are completely out of stock until Jun 2019!?! I might just got with the ECS Geomet Slotted (that do come in "left" and "right" which is noice for the looks department)

Thanks in advance y'll!

I'm curious too as I like the curved slot design which in theory is supposed to help reduce the pulsing feeling you get with standard slotted rotors. I've got a set of 335i calipers waiting for the new season to upgrade on my car and I've had my eyes on these for a while.
