sydneykid, can you please elaborate on your point "...in addition, a 4wd (GTR or GTST) absolutely needs a different combination of stabiliser bars than a rwd." ???
i'd be really interested to help out a friend of mine who had whiteline sways fitted to his GTR and is *only* experiencing understeer (hence my point) take a look...
the rear sway bar is on the hardest setting, the front is on a soft setting (unsure how soft though). i guess i suggested this to him coming from a RWD experience, but your comments have made me think of how attessa would effect this?
the suspension is stock GTR setup, running michelin pilot sports and running about 37psi hot in the front. we ran them higher but understeer just got worse!?
imho, a few things which might help reduce this understeer would be to
- play with rear tyre pressures?
- go softer setting on the front?
- change driver???
thoughts? of course this is just using swaybars, as explained, no camber or castor adjustments are allowed since the gear isnt on the car...
in my personal experience and coming from RWD, i had a full whiteline handling pack fitted + rear diff brace running on toyo trampios r1r's which a are a hybrid semi slick and street tyre. handling was pathetic, from a stock setup where i could induce oversteer it went to full understeer!
back to the drawing board, i had fitted a front camber kit (at -1.75 degrees) and set the rear swaybar on the hardest setting - results were pretty good, handling still has a touch of understeer but its predominately nuetral now. tyre pressures help alot running about 36psi hot in the front.
my next time down to wakefield park im going to have the front sway bar put on a softer setting (as i think im on the 2nd hardest atm) and play around with rear tyre pressures....
