The RS16i S1 and the Rare Turbo Technics rollbar setups designed for the Mk3 Escort gearbox.

These rollbar setups have a seperate tie bar which allows the change of the castor angle.

I.e where the wheel sits in the arch, forward or back in the arch.

When using this setup the rollbar is seperate to the tie bar, unlike a Mk4 where the rollbar and tie bar is all one and has no adjustment. Very crude, cheap to produce and not good at all. All the Mk4 escorts have the same design from a 1.1 to and RST. So in other words you would have the same setup as an escort popular.

The RS16i Rollbar bracket setup is made from an alloy mix making it very light, it also has a very large rollbar compared to the S1 item. It also is a one piece casting which has no parts to bolt together unlike the S1 item.

The S1 rollbar bracket is made from steel, which is heavy adding more to the front, also rusts if not covered.
The connection between the two corner brackets is made via a tube section thats bolts to them. This also cracks and breaks.


So the ideal setup is using an RS16i rollbar uprated oversize tie bars with billet rollbar to tie bar clamps, with adjustable TCA's, MTX75 Gearbox, 16in wheels and decent coilovers.
