put some decent tires on it mines handles its self pretty well , its better than my old golf but it aint no go-kart. On winters you will get stuck by ground clearance before traction is an issue. the only time ive been stuck in mine the front end was up on a drift and the wheels were about a foot off the ground 😀
you got shafted at 500 quid for a rear axle – although i did hear frazer brown is no longer doing uprated ones (which in reality are just refurbed drilled and tapped for grease nipples)
It is possible to drill and tap the original axle for grease nipples without disassembly. Ive done one – i need to get round to the other.
mines are 54 and 06 plates.
My heads up would be for the mk2 steering rack , the angle of the rack pinion is such that water sits and corrodes the seal surface on the pinion and thus it will leak. This can be prevented/minimised by cleaning , drying and greasing round the pinion periodically – otherwise your looking at 200 quid for a recon rack and about 4 hours labour to pull and refit as you have to drop the subframe – its not fun.
Seal kits can be had from “steeringseals.co.uk” but if the pinions corroded your pissing in the wind.
