Yeap, think of the expansion tank as a shock absorber. If filled to the correct level it shouldn’t spill over to a recovery tank.

(Going to use a 1 Liter for the expansion tank and a 2 Liter for both the recovery and intercooler tanks. I ordered black anodized, but they also come in natural aluminum and red anodized.) Joel, I would use the 2 liter for expansion and the 1 liter for recovery. I have a 2,7 liter expansion...

Thanks Ken./J

Ken, do you have a part# for those Moog tie rods?

Does’nt matter if you’re doing street or highway driving. What matters is what engine you’re using. The Graz is geared for a high revving Audi/Lamboghini V8/V10. So if you’re using a US V8 (GM, Ford or Hemi) you want the 1.04:1 or 0.90:1 gear. The 0.90:1 if a lot of highway, the 1.04:1 if it’s...

Don’t think so, but it might be a diff between the KVJ and KBA. Just to recheck I went out in my garage and had my wife to turn the input shaft while I watched the gear inside the sensor hole turning. I then put a screwdriver to ”lock” the gear and she couldn’t turn the shaft anymore. The...

Dan, I’m not sure that’s a VSS. I tried that a while ago and if I remember correctly it follows engine rpm not driveshaft rpm. At least on my Graz KVJ. According to Audi it’s a shift sensor. You can try it by removing the sensor and watch the gear inside while turning the input shaft. The gear...

Scott, if you use the dowels in the end of the crank, the holes are drilled with the damper installed so alignment is not an issue.

Dusty, hard to say from your pics but you really need some kind of vibration damper to the tank. I have mine laying on 10 mm of foam/rubber and the same on every mount. It’s not advisable to just screw it to the frame. You will most likely have have a leak.

Jeff, When it comes to RCR parking brake it was just not enough clamping force to pass inspection here in EU, I don’t know about the E-Stop. I went with the Tesla EPB and bought a controller online, very efficient as parking brake not to be used above 10-15 km/h. That is not an emergency brake...

Thanks Joel.

Anyone have a clue of the diameter and spline count of both the steering column and the rack as delivered with SLC and the GTR?

Time for an update. Body is now off for paint and upholstery so I made some improvement. First out was a speed input to the ECU. I used the inductive sender on the Graz (on the aft left side), first I thought it was a VSS but it turned out to be sender used for shift signal on auto transmission...

Joel, I would say 250ft/lb. I recall that I had to borrow a larger torque wrench, my own ”big one” only goes up to 220ft/lb (300Nm), so 250 makes sense.
