House's ITB XE build and re-build

[House]

Looks like mine. Yours is probably better though if it was made by Ben at Hangar 30.

Yeah it was, yours is better as it's made by you!! I have to pay people to make things!!

His looks like yours? Whose was built first?

Not sure, but at a guess the one that VW Motorsport made back in the early 80's?

Hahaha love it!!!

Love the beam, how much did it set you back by?


I've been tempted to buy the ARB and make up some mounting plates and weld them to my beam, but was unsure if I'd then need the rose jointed arms for triangulation strength?

The beam cost enough!! Well into 4 figures after sourcing the beam, new discs, pads, calipers, wheel bearings, handbrake cables, all new braided lines, fittings and clamps and the work carried out but it's proper!!

The rear ARB is a Saab effort, 9-3 i believe, available from Ebay I'm sure it's BMC motorsport that sell them.

You don't need the triangulation with an ARB, what the triangulation is trying to eliminate is unwanted toe and camber changes mid corner. Camber more than toe in truth. The additional ARB just stiffens the flimsy beam up.

Doesn't look like it'll be done for Cadwell now as the calipers are 7/16-20 UNF inlets instead of M10x1 as I'd predicted, new ones on order but I'm running out of time.

I see how it will prevent or hugely reduce the toe change, but as it's bracing at the bottom of the arm, I can't see how a camber change will be prevented.

The camber change is, hopefully, prevented by that fact the ends of the beam can't twist as they are now braced below the wheel centre line.

[Stuart]

Could it give them more chance to twist as the moment of movement is no longer going into toe and camber, but camber only?

I'm sure it's been thought through well but to my idiot eyes it doesn't look like it solves all the ailments listed. Granted we are starting with a shit design in the first place so that won't help

I think the idea is that there is a support below the beam now so if we imagine looking end on at the beam from the back of the wheel we currently have an L where the bracing turns that into a T (please imagine that the T is on it's side as I can't put on it's side here) then imagine the bottom of the T is connected to the long part of the T with the wheel bolted to the top of the T.

It must help prevent movement around the pivot point/centre of the T

Well atleast I hope it does!!!!
