I go entirely by feel to determine whether the fronts or rears are locking. You can feel the difference in your hands and body whether it is front or rear. It just takes a little practice, but if yo...

@parsonsj Hi John. It was a really fun week. Turn 7 is good because you want to drive deep into that brake zone, and if you overshoot there is plenty of run off. Turn 10 is my favorite for settin...

Update on the temperature strips. I purchased the temp strips from Pegasus.com who I think has the best price on these, $18 for 10 strips: RP-TEMP-230 Racetech 8-Temperature Strips, 160-230 F (71-...

Adding my thoughts to this. The ECU battery keeps track of engine hours so when it goes flat this will be forgotten. The date shown is the last time the ECU was reset. The logbook per entry shows the ...

@davidf Thanks David. I spoke with James a Radical in the UK yesterday. He told me they were phasing out the original uprights. The billet ones were designed because of safety concerns for the SR10. H...

I spoke to Jonathan today and asked about uprights. Cost for original steel uprights for SR3 are about $1100 each. Cost for Billets about $1500. Yes, the lifing for the original uprights is about 4...

Charley, yes I recall talking to you before I purchased the car about the difference in the Life Integrated shifting vs Geartronics. Yes that makes sense about the battery replacement. So that 89 ho...

@e-j-scott I have not driven an SR8, but on my SR3 I like and use the factory settings for ride height, rake, camber, tow. At the track it is easy to fine tune tire pressure, damper, and wing. So I...

The subject of Registry members wanting to know if they have "Standard Axles" or "Heavy duty Ales" on their car has come up several times lately, so I thought it was worth making a post about it. Radi...

@parsonsj ... G'day John. If there's not much diameter difference between them, then maybe you could just build the tool for the larger diameter joint, and then 'sleeve' the roller bearing end using ...

G'day All, I've just completed my first SR3 driveshaft rebuild according to the schedule... done at around 12 hours on my HD driveshafts (on-track time) rather than the 10 hours Radical recommend. Li...

well, my last outing for the year at the wonderful Bedford autodrome. This place is where i drove a race car for the very first time, using their 'palmersport' fleet of cars, waay back in 2007, so it'...

I went ahead and did it. Done by Jet Hot in NC. Not cheap. Before the coating I took a temp reading on a spot on the exhaust pipe after letting car idle for a certain time and getting to a certain ...

@meatman - G'day Josh. Like Charley - I've never heard of anyone having issues like that, and certainly not to the extent that requires any bleeding to be done in the middle of a race event. These t...

Wow, I never had any issues like that. Do you have the floating rotors in the front?
