    A squealing tire is a happy tire.

    Looks like Loren really has taken his racing Mirage to another level. Bravo!

    Very cool thread. His custom sway bar is fairly similar to my design.
    Custom Mirage products: Cruise control kit, Glove box light, MAF sensor housing, Rear sway bar

    Current project: Alternator delete with regen braking modification

    I'm actually friends with Loren. (He used to have a Yaris.) He was a big influence in me getting a Mirage and I've been watching his Mirage build closely. He knows his stuff!

    I am now!

    My spidey senses were tingling. (actually, I got a PM from Andy on Facebook)

    For $600, I really can't complain so far. (though I did fit different front bumpstops, replace the inoperable camber plates with custom caster plates, and am probably running the car an inch taller than most would)

    The hell you say? (and thank you) I skimmed this forum for ideas, as well as looking at the design of the commonly available aftermarket piece. Also found photos of a BROKEN one and opted to make my brackets MUCH beefier. So far, it's holding up well for a part that breaks all the rules. (using standard roll bar grade chrome moly tubing, welding and not heat-treating, etc.)

    This doesn't surprise me as the McPherson strut setup really doesn't like lowering. I remember the Shine racing setup for MkIV VWs which was one of the best in the world for those cars actually RAISED the front a bit!

    Looking forward to having you here on the forum sir.

    Yeah, once you start looking at roll centers and roll couple... the numbers are a lot better with 6" ground clearance than they are with even 5.5". That simple tidbit that you always hear about "the control arms should be level" is 100% true! You don't realize what a difference it makes until you actually make the change independent from other changes.

    In my case, I lowered the car, which screwed up the control arm angle, and put my roll center below ground. (which sounds good until you realize that it just added more leverage to the weight of the car when it tries to roll into a turn) And then I fixed it with a modified control arm and 1.5" taller ball joint. So, when I fixed the problem, I got to feel the effect of JUST fixing the roll center. Night and day.
