Fuel Tank for Sprints n Hills

[Blatman]

Wides and narrows are the same size at the front. My wide track narrow car currently sports a front ARB bought from a member who had it on the front of a wide body car...

Have you asked Luke @ Plays Kool?

Other bet would be to give Procomp a call

When compared to my blade converted to R1 that is quite a difference, the split I have recorded was 48/52.

Made a boob here, that was without driver, with driver ballast of 85kgs it's,

FL 110 FR 110

RL 146 RR 176

So F/R bias is 41%/59% and L/R is 47%/53%, total 541kgs. Data from how the car was in early '09.

so pretty similar then, what sprinds where on yours? did yours handle ok when sprinting?

maybe some arb's and some new tyres could solve it?

That was with 225lbs front & 150lbs rear with ARBs. Fronts 6" ACBs 18 months old, rears 7" ACBs 6 months old. This was with wide track which effectively weakens the front spring, a wide with 275lbs is roughly equal to a standard with 225lbs, so our front spring is relatively very soft, maybe the equivalent of a 175-200lbs front on standard track.

Worth keeping in mind the WF ARB's are very stiff, they resist roll something like 5x-8x more than the springs alone so they really take over in corners. Alternatives are usually weaker.

Generally it ran well on circuits (croft, llandow, ty croes) but was not so good at harewood & thoresby. We had two understeer 'incidents' but both had other explanations. Overall I think we ran too stiff on ARBs and perhaps too soft on springs, but we could balance OK. It's also a compromise with two drivers, I hate roll, Paul hates understeer.

There is surprisingly little info available on good hillclimb setups for westies beyond the geometry basics. Probably lots of reasons for that but does make things harder for setup novices like me who like to understand things rather than take known good configuration. For example, the busa has a zero droop setup now, see here for hints about why this might be a good idea. Maybe Gary Smith can offer some advise.

Some good hints part way downhere

Thanks John, read that one at the time, the best summary I have seen of what the single seaters are up to.

Question is has anyone sucessfully applied the same principles to a Westfield. I am not sure David Gould would advise such given the difference in the chassis stiffness and weight distribution but maybe it aids anyway if you can push past understeer. The raptor handling is interesting.
