definitely

dude your seat is moving heaps ? is that normal

Great power to weight!!! I like how you aren't taking it too seriously and driving through the little slides haha

The fun disappears if you get too serious

Nice work on car antus.

Lol that looks great Antus !
I like that camera angle too.

Ive gotten to the bottom of my traction problems encountered this year..... Unfortunately the plans to improve the car at my mates workshop rapidly went backwards at this point.
On the plus side, once this is fixed, these are ready to go on.
And this should enable me to straighten the rear end up a bit.

Poor little gemini diff

we converted our customers to a shortened commodore unit and trutrac for that same reason, you can buy a torque tube eliminator kit from some where...

I'll do some digging and and find it for you

Nice car

McDonald brothers racing do a kit for that http://www.mcdonaldbrosracing.com.au/geminicontrol.html

Ants already got a 28 spline diff in it, but the axles are obviously not up to the task!

billet axles might be in order!

im liking the look of the tyres though I assume they are nice sticky compound ?

Actually its a stock centre with heaps of nuts n bolts and metal welded in to make it a really tough locker. Stock torque tube is handling the power fine, they just need good rubbers to keep them located as they should be. The axles are commodore axels for the commodore brake conversion shortened and resplined to suit the stock gemini RTS spine. So re-heat treatment of those axels and the lesser spline, combined with the stress of grippy tyres and slow seed manouvering is probably what broke it in the first place. Interesting that the splines didnt shread, just a pretty clean break. Am considering an upgrade, but want to keep it simple and cheap. Replacing the axle and doing it again is looking like a cheap an easy option. If I get 2 years out of the axle thats probably good value.

Or.. I could maybe update to a set of these axels http://altra9.com.au/web/wp-content/upl ... cials5.jpg but would they be strong enough?

Or.. I could take the altra-9 LSD out out the road car and put it in this machine. But im not sure if it'd be up to the task and if I did break it then thats a lot of $ down the drain, and thats resplined commodore axles too. But, 28 spline.

Yes those tyres are looking promising, nitto nt01s. They feel sticky to the touch!

yeah thats it, beat me to it 202 looks like a good kit

I'd reckon that sticker tyres it going to cause more broken axles (I've broken too many to count) remember that the Gemini was a low powered, light weight, open diff vehicle with very small tyre contact patches. Yours is now high powered, heavier, locked diff with very big tyre contact patches with grip that will be awsome!!! Poor little diameter axle ends don't have much chance.

One answer would be to leave the setup you have in there and change to LSD or trutrac (if they make one to suit the small housing), that will take a lot of the torsional stresses out of the axles. As a bonus it will make you faster - take the under steer (push) out of the corner entry and over steer (tail outness) on exit. Locked axles are good for drag racing and breaking axles - thats all...
