not lifted a 2wd but its simple enough with spring spacers front and rear although you need to know how high you can go before you get the dampers to top out.
been told t25 rear springs lower a t4 at the rear so maybe t4 springs will higher a t25 at the rear although the spring rate will more than likley be way wrong.
we`ve semi syncro`d my brothers westy high top on the cheap just by fitting wheels and chunky tyres and the result is good, not as high as my syncro but still looks meaty and is very practical for what he uses it for.
