I have gotten terse advice from them once before but I do trust their judgement. Not to berate the topic here but I'd also recommend using the front swaybar and really its weight is almost negligible; you'd have to be on the cutting edge of 60ft times to be worried about that little amount of weight. And for street manners, I couldn't imagine running without one.
If there was attitude present on their part, well, comes down to that person I imagine. MM has too much to lose in the realm of customer word of mouth and they're definitely not in the business of losing business.
BLUF: if you ever deal directly with Jack (the main dude there), he's the kind of tech that you ought to listen to and heed his advice on things. He knows his shit like few other people do
To address the front sway bar, this is not at all a daily driver.... so far this year it's been driven across town to the pool a couple times and once to a cars and coffee and it handled fine. I may look for stock sway bars down the road and undo the front end links on club track days, but it's just not a priority for the type of driving I do.
The main problem isn't that they were terse, but rather they didn't seem to know anything... didn't have opinions about spring rates for a street and 1/4 mile car, vs a road course car... didn't have recommendation about struts, didn't have a recommendation about anything....
Did more research after this, and I'm leaning towards the MM 12" 250 lbs. front coils, with KYB/Koni non-adjustable struts, and MM caster camber plates up front. Strange has a 200 lbs kit that's significantly cheaper, but appears to be a cheaper made kit.
