Huh? So you mean that MTM who sells and installs WG springs on their
customers' cars aren't doing their job properly now?

Nope they aren't !!!!! AT least on the 3B ECUs they have never been
soldered and never required unsoldering, and even some UrS4 ECUs that I've
seen (they had never been opened, one of them was brand new from Bosch) had
sockets in them. So one more time you're wrong Brett!

That's not true! MTM sells 2.5 and 3 Bar chip upgrades for the 3B AND
install stiffer WG springs without their customers necessarily knowing
about that! A 15$ spring would be a too easy improvement if everyone knew
it, think a little! I've seen the real MTM "Fat 'n' Low" UrS4 that had a
stiffer WG spring from MTM in it, now what do you say to that?

Mihnea, defending the sake of the stiffer WG spring :-)
