UAS HICAS Eliminator Kit

I tried to convey info through Rob but seems to have been confused. I won't comment on anything other than technical items raised associated with the product. I suspect there would be at least 1mm of play due to flex of urethane bushes under load. Not to be confused with bump steer in rear or toe change through travel up and down of the wheel. We plotted this years ago and found full droop to full compression in rear is more like 5mm total change and yes toe's in under compression which in theory is better for traction but may be a bit too much and wear tyres. Through trial and error and testing and plotting different geomtry changes, we reduced this toe change a lot in our race car.

Flex in steering

Hey mungyz I had this set up in my car like NA as has NA cradle and a motor sport engineer a few years back was checking and advising on our car and saw this bush set up and said big no NO. Even if not worn which they actually wear you get flex in the steering angles left to right through flex in the bush. Factory Nylon set up if not worn is better for NA. I had Rod end inner but urethane outer bush and changed to TT ball joint and even changed to R33 GTST ball joint which yes fits and uses a lighter circlip to secure rather than a big this metal and rubber washer and bolt the ZTT uses.



Now have this set up.

 

John, do you think that the bush on the traction arm could have a similar effect? Any work been done on replacing that?

 

Yep factory Nylon if not worn is better than aftermarket Urethane, and if flexes not as much effect on Toe change as rear steering arm. We have adjustable and Rod ends inner and outer as per the pic.

 

I just got tired of the ball joints, when I first got the car both outer ball joints were worn & the rack ends were as well, I replaced all of them then proceeded to abuse the car in burnout displays, drag racing, circuit work etc. It wasn't long before the rack ends were worn & a ball joint worn again.

I have no doubt there is movement in the bush compared to the ball joint & no doubt they will wear also but I have a plan for if/when that happens

 

I can totally understand why the inner sockets would wear as they often do, but the outer ball joint rarely fail or wear. You must be a thrasher. My outer rear ball joints are fine after a few years of racing 10 plus track days a year.

 

Who me?

Never! :rofl:
I think it was the drag launches & burnout displays that did the damage, for normal use the ball joints are fine - I made a special puller to change them without removing the rear knuckles but then found I only used it on my car :bash: :rofl:

 

hey Rob do u have an update...

on the orders yet.
