however a rebuild would cost about $250 - $300 a corner, on average, thats just for new seals etc, if stuff is broken, they go up to about 1k each.. these are aprox costs, from what it costs to re build our proflex (which do contain some DMS Parts).
give them a call on 02 6024 4734 and ask!
DMS are good and if its a good price they are worth it, which spec are they tarmac or gravel?
ive spend a fair bit of time driving an evo 3 with Dms, and they are pretty good for the street, (this was a rally car mind you) and really really make a huge improvement
as for what jon said yeh DMS one of the best, but certinally not the best, but performance for $$$ they are great!
