I was never happy with the way I mounted the dust lights. They were just knocked up at the last minute and hose clamped to the roll bar. Did the job but it's been bugging me for a while so I came up with this.

hay that looks real neat, good looks and all, well done I like it.

Are you repainting the rollcage or just the parts that need it.

Rik.

See how we go for time Rik, I'd like to colour code the outside section of the rollcage to blend it in with the car but I'd also like to re-paint the whole car. So much to do so little time.

IMHO, I like the black contrast of the cage, but it's your car and it always looks the goods.

That would real nice and neat to have the rollcage colour coded with the car, class is the word that come to mind.

Hope you get all the things done that you need to have done for the next race, good luck and go and kick some Chapmen butt.

It would nice to see a Brumby at the top of the time sheets.

Finally got around to rebuilding the rear shock towers this afternoon. I've been putting the job off because I'm planning to get myself a Tig but I'm running out of time so had to mig it all again. Maybe next time?
It's still a time consuming job when you have to notch the pipe by hand and your bender won't work on tight radius bends. Next racecar I build will be in a dedicated shed with motorsport quality bender & notcher. Oh and a guillo and a press brake and and .....

pics to follow

Definitely need to step up to a tig (or employ a fabricator with one).

Thanks dude. I'm in a sport where the norm is unpainted tig welds so everything's on display. But I'm not the only farmer with a mig either.



The gold rollcage does look a bit :shock:

With the shock mounts finished I cycled the shocks to check the CV travel. It's tight but I think they'll survive.

looking good! that's alot of travel for those poor CVs. does the diff touch the ground when it's fully compressed?

I kind of like the gold on the bars.

Are you using the MTR's this year or have you decided on some thing else?

I stand corrected, gold looks good too.

Well it would depend on the tyre size but with 30"s it gets down to 3" at full bump.

The only problem with the MTRs is that 3 of them are getting on a bit. We replaced 2 last May so they're only 1 year old but the others must be pushing 4.
I'd like to run 16" tyres but there's no point buying new rims if we're changing stud pattern.

Looking real smart in the gold Stuart, that gold rollcage looks even better then I thought it would.
I like what you have done with the rear, How did you go with the front X member? and will it be as strong as the rear?

Rik.

I built a stronger engine crossmember after Finke last year when the old one cracked up.

I'll eventually replace that with a new fabricated one that'll house a Howe steering rack and new, longer, wider track lower control arms that'll have full movement without binding, like the radius rod setup has now.

2nd pic is fine mate, not just talkin bout seeing it but also what i am seeing... would love that sort of travel without my crappy rear camber issues....

cheers

That's strange. All I see is a grey square and the code is fine. :?:

To get that much travel without binding you have to ditch the factory camber change rear end. It's entirely possible to build a new camber change design that allows full suspension travel without binding but mine is fixed. It maintains about 3 degrees negative camber throughout the 14" of wheel travel.
