Can anyone answer this question
Can I fit a caterham Rollcage to my GTS with slight mods

I'd imagine normal Caterram no, wide body maybe
Slight mods? Hmmmm

Assuming that's your car in your avatar pic, your best bet would be to have someone like MK Engineering (Martin Keenan) make the extra parts to suit the car and make use of the existing roll hoop, which already looks braced to the rear. Trying to modify an existing cage to fit s sure to be more grief than making something to suit (IMHO).

Give Nigel Keates at Cougar engineering a ring, he fabricated one on my Striker off of the existing roll bar, quality job and not silly money.

As a side, is the GTS any good as a track car compared to a Striker as looking for something at the moment?

Thanks for the info
I'm no racing driver but I think it is very good,
I'm running a R1 turbo engine, R888, Protech shocks
The only problem I had was the rear wheels rolling out at the top so I put shimms in the rear hubs
