The Castor rod/Radius rod conversion that 1200coupe uses:

The Holden wrecker I went to swore that the radius rods were the same for LC & LJ so I just grabbed a set despite the angle looking very wrong R/rod comparo The stockers mount diagonally: stockers But the Torana ones look to be spot on when you mount them on the parallel bolt holes: Torana rod Possibly the bolt holes are different spacing for the LJ vs LC models, because these ones will need a bit of work to fit

The motor is a little rocket with forged flat tops , everything lightweighted, blueprinted, balanced, ports, cam, twin 40mm sidedraft, extractors etc - ran about 72rwhp and about 85nm. Clutch is big clamp load with good organic plate. Gearbox is standard 4 speed with complete rebuild - bigger bearings, drilled and cut synchros etc The vehicle used to break the standard universals on the start line so we had to build a bigger tailshaft and are using this. The race car is using a Toyota T50 3T box which is handling the power so far

Ah yes - but we have just finished building a road car from the ground up - registered it last Friday.
A real road car with no special mods except for the drive train - we had a spare 1220cc race engine, clutch and box sitting around doing nothing so we popped it into the new road car - and succeeded in getting it through engineering with no major probs as it is a 73 model with the early lack of polution requirements. As I said it was a ground up so has turned out pretty well. It will pretty much be a daily drive Quote:

*bump* - the castor problem is sorted but ahs anyone found an upgrade with decent camber characteristics without using plates?

Adam BDA- you are on the money there, I am starting to wonder why the hell I am screwing around with a road car. Everything is such a massive compromise...... can't have castor plates, cant have trackwith increases, can't have the wheels you want..... aaarrrrgggghhhhh Ah yes but be warned - getting involved in racing is a bit like being a Pelican...............everywhere you look there is a bloody big bill in front of you

If it is a road car it is all different as far as rules - but for our race car we pulled the cross member out and redrilled it to a different position.
The maximum allowable under IP rules is 25mm from the original point. Then fabricated a set of strut tops to allow us the caster and camber that we wanted. We kept the new holes to a height such that the lower control arm was sitting flat at rest.

I wouldn't be concerned about the strength of the standard castor/tension rod unless you are intending to rally the car. They simply hold the lower control arm in tension. Any shear force present in that rod is negligible.
On my coupe, I simply had my standard 1200 castor/tension rods threaded and used a nut on each side of the mount. Must have been like that for a good five years including alot of bouncing off ripple strips, the odd excursion to the infeild/outfeild here and there, and a couple of incidents with a bank at Mt Cotton which tore a castor rod mount off the chassis, and a kerb on a road rally which sent the car airborne. Neither damaged the tension rods. No sense adding weight where you don't need to.

I'm not sure of the legalities, with a big washer, who is to know? I asked about this at the suspension shop. the answer was " not a bad idea mate, but do it after it has been through the pits" Highly illegal to move pickup points. They also reckoned If you move the LCA bottom mounting point up and out it will bump steer really badly, so you would have to bend the steering arm down by the equivalent amount, to keep the LCA and steering link parallel
