No one has spoken of a rear anti roll bar? I have fitted one on my car to try.
Conventional wisdom is that a rear ARB doesn't always work on a live axle and I have to say that it has made the front feel vague now, although the rear feels good?
It is running Spax dampers and springs and some polybushing (replacing standard material when they wear out!)
As the car is mainly used for rallying and limited to 70 series tyres I don't have the luxury of grippy Toyos (although I do have some 60 series Yoko`s when regs allow).
Does anyone have experience of uprated front ARB`s? in years gone by I have made up twin arb`s on Ford`s (a common mod back in the day when parts were hard to come by)
I'm running a rear ARB on my own road/track car, just a stock Sprint one and I think it helps more than hinders. But my car is so far from from stock, with it's Vauxhall powerplant, lightened, short tailed, 2 door body, altered CofG, modified suspension etc, that my experience is largely irrelevant!
The factory circuit cars, compelled to use a rear ARB (because the production cars had one) used one that effectively was a piece of piano wire that did nothing - Which may be a clue to the works engineers (and the drivers) opinion of how needed it is! But AFAIK the works cars all had LSDs which also affects handling and balance. The wisdom around here, such as it is, seems to be "suck it and see" some prefer with, some without, depending on how "loose" they like the tail to be!
There is an almost mythical, fatter, front antiroll bar that was allegedly fitted to very early Sprints but dropped almost straightaway in favor of the now standard one. Or it may have been a short lived ST part. Whatever, it's only ALMOST mythical as examples DO exist, but are less common than hen's teeth! As far as I am aware, nobody has produced anything like it for the aftermarket, which, I would say, demonstrates a lack of demand (or need)
