How "stable" is your car on the open road???

[David Hodgson]

Get rid of the toe out. Toe out can help 'turn in' on the track, but on a rear wheel drive car on the average Aussie road is not good

1 -1.5 mm Toe in with around 3 degrees caster should be a good starting point for street.

I experimented with alignment setting a bit for the track and toe out seemed to help a bit on turn in, but was very nervous under brakes. On the road it was wandering all over.

My RMC was running around with these figures for years:

Front
Camber: -0.5(L) -0.5(R)
Caster: 4.0(L) 3.6(R)
Toe in: 1.0(L) 1.0(R)

I'm not sure yet what I will run with.

Yep..pretty close to my start point for the front Craig.

If I remember the previous owner told me the car was great on a smooth highway by a bit nervous on an undulating road.

One of the problems with the RMC is the variation of the placement upper arm mounting.

My car has the two bolts holding the upper arm above the bottom of the front chassis cross member. If you look at the picture in Ross Smiths gallery at his chassis pic you'll notice the same holes are below the cross member.

Whilst not an issue at rest Ross's car will invoke negative camber with less body roll which is exactly what you want.

Sadly the RMC chassis varies quite a bit.

As you know my car has already got some and is getting the rest of Scott(Ozvenom) RMC Enhancement package.

In his words, it will be a pleasure to drive on the road. I'll look to Scott for guidance on the wheel alignment settings.

And the same fella will be doing mine Craig. He has already done a little bit.

But that's exactly my point....Scotty is a wizard because he:
1. Knows the cars
2. Attends to the detail.
3. Makes the required changes.

He was the one who drew my attention to flattening the upper arm. Since then I have noticed the variation between RMC's.

Both the RMC and G-force ( being closely related) can be made to be an absolute pleasure to drive. Dare I say, ( and I just know I'm gonna cop $hit for saying this) that the RMC, ( and G-force by implication) properly set up are close to the best street cobras you will find.

There, I said it.

All sounds good guys, but....

I went from complete nerves on undulated roads to complete confidence by simply replacing the Falkens with Toyos T1R's.

I have absolutely no wandering at all now.

Grips as good as the WRX! (Well at least 2 wheels at a time).
