Vixen ARB mount / bushings

[280i]

I have a 71 TVR Vixen 2500 (vixen frame).
I just sourced a larger 7/8th inch front anti roll bar (from a spitfire). I am hopping that this bar will be a better match for the heavy TR6 motor up front.

I am in the USA and have found a supplier that sells some very nicely made ARB mounts containing nylatron bushings.
I have seen solid ARB mounts in the past that were crudely made but these look much better. I have solid steering rack mounts from this same vendor and I am very impressed with them.

Question - Do folks think this mount is an improvement over the stock rubber and U-bolt design? Also will this put more stress on the mounting points of the car (the car is not raced). I would hate to damage the frame by doing something like this.

Please let me know your thoughts.
thank you

It'll be fine!



My basic understanding is that on something like many 60's Fords with McPherson strut suspension the anti-roll bar alaso plays a very important part on locating the suspension so forces will be transmitted into the frame.
But on a double wishbone set up (TVR etc.) you could actually run without an anti-roll bar and while handling may be compromised everything will stay where it should be. those brackets merely locate the bar, all torsional forces "pass through" from one side to the other?



Shoot me down if I'm talking bolloc nonsense

Look grand ... but will be that bit closer to road !!

Good point I will have to see if it will be closer. Regardless I think other things scrape first on this car. Looking to have exhaust done in the near future.

Parts from this vendor are first rate but he mostly supports the TR6 crowed.

Won't you also need modified drop links if using the spitfire ARB?

I am already running rose joints (one male and one female screwed into each other). I am thinking those should work fine as they allow more adjustment. It looks like a close match from the Spitfire bar and the Stock one.
I should be fine.
Bigger question is how will the car handle with the bigger bar. Do folks use rear bars on these cars? if yes how do they mount them?

thank you

Is the ARB you have an exact replacement? The Vixen ARB's were TVR made and the 7/8 spitfire one I have under the bench is a different profile and certainly wont fit.....

It's not 100% the same but very close. I think it will work. I will report back to the group when I fit it.

Interested to know, its just I recall the ends weren't anywhere near where they need to be, even with Adrians rinky dink drop links.

The spitfire bar is an exact replacement on my car. With the exception of the mounting brackets. I will be buying the alloy ones depicted above.

It will be interesting to see how the car handles with the larger bar.
