Last weekend was round 1 of this year's Tasmanian Circuit Racing Championship at Baskerville Raceway, about 30 minutes drive from Hobart. It saw the return to the track of @rjbender fresh off winning ...

I have set up an SR3 two seater and it was impossible to get rear corners close to equal without sacrificing the front corner weights. I set the springs according to factory setup, and adjust the pus...

Agreed, the AiM stuff is way better than the 15 years old Stack stuff. That's why my Stack dash is in a box! Anyway, do let us know how the install goes. I found the MXS to be a tight fit with all the...

@meatman, great choice!

Josh, I've got a refurbished Stack dash from my 2009 SR8 with a new battery. Let me know if you have any interest. @meatman

I just bought SR3 0925 from Robert Burgess for track days which I now enjoy more than vintage racing. With 50 years of British race car history between the 2 cars in my garage, I think the SR3 will ge...

Hi Josh -- I'm a tinkerer too, and I agree on it being half the fun. I wanted to install a clutch actuator this past fall (my track "season" is from December to May), but I couldn't get the vendor to ...

I spent this winter redoing the exterior. Chassis 789, removed ‘Spider-Man’ wrap. New engine install next week. Attachment : 0C70C427-AEAB-4A43-8D0B-E9D4CC77159E.jpeg Attachment : 06D054...

The tires are directional marked. I talked to Hankook about this exact subject, they said the tires are intended to run in proper noted direction for the 1st heat cycle only. After that, they can be...

@kirk perfect, stick with the output shaft you have then. The shafts for the selector forks will already be billet. The selectors forks will currently be OEM, every Radical engine uses OEM ones as sta...

I'll take a stab at this although I don't really know. The top speed of the track appears to be pretty fast. My rule of thumb is to match the top speed of the track with the top speed of the gear ra...

As mentioned this is normal, due to the design of the gearbox. The gears all have 'dogs' on which engage with each other as you shift gear. This all works well as the gears and shafts are all spinning...

@meatman G'day Josh, I certainly did.... here's the process I used but I'd be interested in anyone else's views if I missed any tips/tricks... - Fill with oil in the dry sump tank to between the top ...

I used a pair of large pipegrips on outer shaft but had to machine 36mm 12sided socket to fit centre nut clearance .. also used 2 grub screws (allen key ) that locks against the flats of nut ...

Early Busa's (99-01) didn't have these washers fitted as standard but everything else did. Radical leave them in everything and fit them to engines without them to assist. Having said that you should ...
