Given the fact that you can have Extrude Hone 3x hone the standard 2.5 UIM for 285.00 and that the 3x UIM will flow better than the stock SVT UIM...the performance market may be gone as far as the top end dollar.
I know I would have gone 300.00 for a SVT UIM, LIM combo just a few weeks ago. Now, I just passed on the LIM for 90.00, those are still fairly well available and have found them in the 45.00 range. I bought a "spare" standard UIM (25.00), will send that to EH for the 3x treatment and shop for the cleanest SVT LIM while I am waiting for the UIM to come back.
As far as powder coating, if that is a desire why stick to the stock black (although that would be my color of choice)when you can have any combo you want.
