Thanks -- found some at McMaster-Carr. I'll have 'em tomorrow.

Hi guys -- Does anybody have a product recommendation for marking positions of nuts/bolts to watch for loosening? I've used Sharpies and they work OK, but I'm wondering if there's a better, more visib...

I can ask my guy at Wilwood, but I will guess his response will be "no"... I'll wait to try and get that information once I get my front rotors off the car.

Richard, with a new set of 280mm steel rotors in hand, if you can provide dimensions, I'll be able to work out if Wilwood stuff might work. The biggest problem I see with Wilwood's catalogue is a lack...

I heartily endorse Driveshaft Shop. I've had a lot of work done there over the years.

I re-used the Radical shift block and wiring connector for my MoTeC conversion. My notes show: UP -- power = red, signal (ground) = blue DOWN -- power = red-black, signal (ground) = grey

The shifter block uses 4 wires (2 for up and 2 for down shift). Each side should have a 12v supply, and the ECU (or GCU on older cars) pulls the corresponding wire to ground to make the shift happen.

I just got a reply from Wilwood: the best thing you can do is comb thru my offerings and see what might work for you. I don’t have anything off the shelf, as a 10 bolt pattern is not common for us. L...

Ah -- I've not measured mine. You're right: if the steel rotors are 21mm from the factory, that's plenty thick. I reached out to Wilwood with the dimensions you posted above, along with a note about ...

Charley, that's good stuff. It fits with what Wisko Racing told me a couple of months ago. Have a look in the alternate parts area for a link for where to get replacement boot clamps.

Not that I'd recommend this course of action for others, but these were the sort of issues that led me down the path of a complete ECU replacement.

I think the .81 (21mm) rotors are too thin for our use -- I'd not want to go there, especially on a front rotor. Did you get prices on new rotors from Hi-Spec? I can also make contact with my Wilwoo...

I'm back in town today, and should be able to get some measurements.

I'll be back in town early next week, but it seems that swapping to a Wilwood rotor is not straight-forward. I think the mount points are different -- Wilwood use 6 or 8 fasteners rather than 10.

I was looking over Wilwood's catalogue and came up with my own set of related questions: what's the dimension of the mounting tabs to the hat? Bolt center and number? Rotor thickness? It also seems li...
