Club Triumph

Can anyone tell me if the addition of an anti-dive kit will pull the wheels forward into the arch? My front driver's side wheel is snagging the lower front part of the wing on full lock when reversing (the bit in front of the arch that curls under).
:-/

With an anti dive kit the front pivot point of the ARB is lowered.
But the arm length and the mounting point on the TCA remain the same.
This means your castor angle will be reduced slightly, positioning the wheels a little further backwards.

Sounds like your cars castor angles vary L/R so the front wheel alignment needs checking.
Castor can be adjusted on these cars by loosening the ARB saddle mounts such that you can move it L/R
Make sure it is equal L/R. Sounds easy but isn't, it can be time consuming.

And fitting wider wheels and tyres can highlight problems in this area.

Many thanks .

This sounds like the most likely issues since I've just had the front end suspension rebuilt
