Mythbuster: continuing project thread of my 1303 '75

[judgie]

what camber are you running at the front? i found the best set up for mine was to have the rear quite soft and the front fairly stiff.
run 130lb front springs and a h/d bug pack anti roll bar, rear bars are 944 and the 944 anti roll bar. front camber is -3* and rear is -2.5* front toe is set to 0 and the rear has 1.5 toe out.
it will pick the inside front wheel up but at least thats getting as much wieght as poss on the powered wheels which helps combat the wheel spin.
i found that high speed corners were improved when i fitted the front spoiler and splitter and improved again when i fitted the dive planes.
guessing this will all change now i have fitted the lsd.

My set-up and car are probably not really comparable..:
Your rear 944 torsion bars are 23mm. I run 25,5mm (M030) bars.
Your rear 944 anti roll bar is what? 17mm?. I run a 24mm Whiteline anti roll bar in the rear...

My front springs are already 50 lbs up over what Lee send them with. IIRC I now have 350lbs springs...

That why I said each car is so different. Mine is probably so much heavier and therefore needs more of everything I guess.

Wow... you are already running a pretty tight rear.

How about replacing the side and rear windows with Perspex to reduce the high up weight? Or would that cause legal problems with road use in NL?

Like the the "I'll be baack" style glasses

Also remember this front set up is our fast road not our full on track set up.

You found me Bruce

and I already have lexan sides (door window, rear sides) and rear window..

Yeah, suspected as much, but really I probably would like this set-up better anyways. It IS after all really not a 'full on track car' either. I drove 2 hours one way to the track, so _some_ suspension movement is desireble still just to arrive fit and be able to 'race' in good spirit

and the very next day/evening I was on 'drive-my-friends-to-be-graduated-son-to-pram duty' :



running at idle for over half an hour in queue...he was happy though

Looks like you had a fantastic time Walter, thanks for posting the results.

In your opinion, for the type of driving you have done on the long tracks, would you consider adding a limited slip diff ? Or would this potential addition not be worth it ? How about for the drag strip ?

Thanks.

Good question! short answer: YES!
For last monday I didn't really missed it, but then again, I can hardly tell what its like with one.
I have missed it before on the circuit when I mistook inner wheel spinning for clutch slip (the latter it wasnt). Now with more spring and less overhang, I can get away without it or so it seems, but still wished I had it onboard.

For drag racing I really miss a Diff, any diff I would say as I almost always get one-wheel burn-outs which really sucks and is almost dangerous because of the different traction left-right it results in.

If I get a financial break, an LSD from Paul Guard is the first thing on my list 4sure!
