Torsion Bars/ARBs - Sizes and Sources

[powerandtorque]

GTI6 - TB 20mm ARB 24mm

For what it's worth, this isn't just GTi-6 that runs this configuration but also XSi, S16 and Rallye.

306 estate - TB 20mm ARB ?mm

Not conclusive as it's the only one I've stripped, but going from my '99 HDi estate they use 21mm rear ARB's.

Xsara VTS - TB 21mm ARB 23mm

This isn't entirely correct - Phase 1's and early Phase 2's run 21mm TBs and 24mm ARB going from the several that I've stripped, and I think it's only the later Phase 2's that use a 23mm ARB.

To add to the list:

ZX Volcane - 20mm TB 22mm ARB
ZX 16v - 21mm TB 24mm ARB
