Just been poking around underneath the Griff,and have noticed the nsr anti roll bar plate that resides on the rear suspension arm is broken,well split in two actually where the rubber bush's pass through it from th drop link,this looks like either a new arm is req,as the plate is welded on,or strip and try to weld the plate together/plate either side..... but i recall reading there was a debate regarding the validity of retaining the rear arb at all? some think the car is better without one fitted,a more controlled break away of traction rather than suddenly letting go? if this is the case,would i just be better removing the whole thing anyway and not bother with the repair?

I presume that the bracket is a Mk1 version...the Mk2 bracket is 22.00 ukp (plus P&P) plus a bit of proper welding (as the ARB bracket and wishbone tube are different thickness) the arm can be removed with 4 bolts and 1 nut so you can work with it off the car.

Not sure if its a mk1 or mk2,but its a 95 500...... as someone else has pointed out over at the tvrcc (jools i think) as the brackets broken,the arb is doing nothing at the moment anyways,so removing it would make no difffernce to the way the car has been behaving since it went (not sure when)...... i think ill whip the wishbone off at the weekend and get it repaired,i did a search and found a thread where steve heath commmented that removing the arb resolves some issues,but adds others that may not be desirable.Adrian@

If i were you Martin i would get it fixed mate 
Hows things are you still enjoying Griff ownership then ?
Hi Paul..... yea things are still great with the car,more time to use it would be good,but cant have everything,ill deff get the wishbone fixed,can get it welded at work so no problem,just wondered whether it was worth bothering with,or just remove it..... as always there are differing opinions on here.... also scouring the internet for some wheels for it as i really dont like the ones on there.Hows things are you still enjoying Griff ownership then ?
Cheers... when my (Mark I) ones fractured, I just junked the ARB fully intending to repair and replace it all as soon as... Won't rehearse all the arguments etc but suffice to say it never happened but one day I might with proper droplinks and stiff crossbraces - they look much improved

I had this bracket break on mine. I had it sorted and think it handles much better with than without.That said, I added the drop links at the same time, which helps.
Before deciding what to do, take a good look at the state of the wishbones generally. If they are generally starting to rust then get new wishbones with the later type mounts.
Someone on here posted that they do hill climbs. They said they have found that it’s better to run with the rear ARB connected in the dry, but disconnected in the wet.
Watch out for the welding on these. I let a Kent TVR independent loose on mine. Not happy that he managed to give me the car back with a small accident. He had blown a hole in the wishbone with the welder.
I was less than happy about being given a car back that was in danger of collapsing because he had structurally weakened the wishbone. If anyone wants to know who in Kent hands cars back in a dangerous condition due to their incompetence, drop me a PM.

Question is how did the plate break like that ?
From the photo, its doesnt look corroded so the ARB must have had a massive force to break. I would have thought the ARB would bend too much to exert that force on the plate & the suspension would lock-out else where.
It’s not a single massive force as one event, its lots of little ones.From the photo, its doesnt look corroded so the ARB must have had a massive force to break. I would have thought the ARB would bend too much to exert that force on the plate & the suspension would lock-out else where.
The early brackets develop fatigue cracks, which then break. It’s not a case of one big impact breaking a healthy bracket, probably an above average one finishing off the weakened one.
Picked up my repaired wishbone last night,the lad who welded it was pretty damming about the design of the original,and was not suprised it had let go,he added two rods to the sides of the repaired bracket to add stiffness,but did say as pointed out above the other side will go the same way due to now being weaker than the repaired one.... so im going to get the other side side off,and get him to do the same thing to the as yet non broken one
i have the same problem, getting a bit common this one
