It's the carbon piece -- the stem -- moving on the mount pad. I think the housing/mirror surface are ok.

Hey guys, I'm looking for advice on mirrors. I ran at Sebring yesterday and while I had a great day, I struggled with keeping track of traffic behind me. I was running with about 3 Porsche Cup cars th...

Yes, that's the recommended oil from the latest SR8 Owner's Manual. It's green in color, and available at Amazon.

This came with last summer's purchase of an SR8. It must be the original shifter mechanism, and it seems I have two handles and intermediate linkage. Anybody interested? Attachment : 20191229_223...

I might be the last to discover this little tip, but I was stumped when trying to replace a body latch on my SR8. My rivet tool (the nose) was too big to get to and hold the rivet in place. After a fe...

The calipers bolt directly to the uprights -- there's no bracket. And since you don't have to swap uprights to go from 280mm to 300mm brakes, I figured it must be the caliper. But I didn't know that S...

Are the calipers for 300mm or 280mm brakes? I might be interested if they are 300mm versions.

The winter rating of motor oil in racing engines doesn't mean much. I'd guess Radical wants 50w oil to provide proper pressure at temperature at racing speeds, and the Motul and Silkolene came as a 15...

Recently I talked to Dave Mansfield at Hewland who told me about this new gear oil that they now recommend: the best part is that they say gearbox warmup is no longer required.

My SR8 water pump has a switch on the dash. Oddly enough, the wire that feeds the switch is labeled as "Fuel Pump" 🙂

It's hard to tell without feeling the bearing surfaces (do they catch your fingernail when dragging it across?), but they look pretty good I'd say.

Yes, please: let's see more about this project!

While I had some gearbox controller / ECU integration issues, I took #87 to Sebring and ran a few laps -- a couple at speed even. The best news is that the new brake ducts worked without rubbing. I th...

Here's the MXS in #87 SR8. The alarm that's on is for low fuel, which I programmed with help from Matt at Trailbrake. Many thanks! Attachment : UNADJUSTEDNONRAW_thumb_11fe.jpg

I'm continuing to get SR8 #87 ready for the track, and I was dismayed to find that my fuel bladder had expired in 2017. Charley recommended Harmon Racing Cells in California, and they had one in stock...
