I am wondering if it would be smart to change out the stock front anti roll bar on a vixen 2500 to a 7/8ths bar. From what I know 1.6L Vixens have the same front bar as the TR6 vixens. The thicker bar may help with the extra weight of the TR6 motor in corners.

anyone have thoughts about this?

thank you

I made myself a 22mm bar (near as damn it 7/8") for my Taimar from a Chimaera front anti-roll bar.

Wise move. Too many folk try to stiffen springs and wind up shocks to do the job of the ARB. I ran a 1” front ARB on my race m and it always cornered nice and flat.

I am sure the 800lb springs also helped that though John hehe

Shortening the arms (levers) is similarly effective.

This is how we did it in "the olden days" wink

Clamped two together on a Sunbeam engined Hillman I ran in late 60s, great until the original single bar snapped and I took to the scenery!

Will making the front bar stiffer without a rear bar cause problems? I would hate to have the car under-steer more due to this.

............. confused


It did work for me, thicker front bar and no rear bar did not upset the handling or increase understeer.


Having said that the Taimar is my tootle around on a Sunday morning car, it doesn't (usually wink ) get thrashed !

What's the advantage of a larger anti-roll bar if you just do Sunday driving.

For me the advantage is there’s no disadvantage.

Bar does little during normal driving but assists reducing front end roll on track.

it has sure an effect on the handling:

on a RWD car a stronger front ARB usually reduces oversteer and will make the handling better (more neutral)

but there are RWD cars out there which came from the factroy with understeer (TVR´s not, i guess)...in that case a stronger rear ARB would make the handling more neutral.
