Updated alignment settings

just looking at those Geo figures, that's a ferocious amount of toe out up front, 1mm per side 2mm total, although better for turn in, does the vehicle not tram-line badly and somewhat unstable in straight line driving ??

I've had about 100 miles on this setup on the street with OEM sized front tires and I did not experience any tramlining and it was perfectly stable at ~85mph. I'll have track feedback in a few weeks.

I wouldn't say that's a FEROCIOUS amount. I ran 1mm and it was rock solid and turn is was like a razor. Of course at 150+ you feel some wandering but nothing that is out of control.

Dell I respect your experience and ferocious it might not be but a lot it is..

What is wrong with zero front toe? Or if you must -4' total for that edge on turn?

Even cups and RSR basic settings are zero front..and they are the epitome or razor sharp..

When I tried negative , car was tricky.

Just saying.. : )

I received some Excellence magazine from a fellow Rennlister (when he is clearing out his garage or just want to share the magazines with others.. he just charged the shipping fee, I got 15 of of them)..

Anyway, I was reading the Cargraphic 3.8 GT3 review that won the Tuner Grand Prix.. it was running toe-in (slightly) up front. I was kind of surprised.

Anyway, just a reference point.. !

I don't have my secret decoder ring for minutes to mm. What does 4 minutes translate to in mm?

Zero toe is just fine but running a touch toe in not only provides better turn-in response, but dials out some understeer. For those of us that like a car that oversteers a touch, then it is a great setup.

It's not for everybody. But if the race teams run toe-in, there must be a reason. My shop rec'd it, so I listen. All I do is tell my engineer what I want the car to do and he sets it up.

I'm not that sharp on setup, so I did like what Dell suggested;

"All I do is tell my engineer what I want the car to do and he sets it up."

What I do see is that people seem to get caught up on just 1 piece of the puzzle; its camber + toe + caster + tires + driving style + down force + ability (I'm no Cup driver!), etc.

If I go out on track and can't find my *** with both hands, we change change it

LVDell

That's why it's great to have somebody like Greg (we have the same engineer). He understands our non-engineer speak and translates it to what we want the car to do. If we don't like it he changes small pieces at a time.

Scott now has a phenomenal baseline setup for the track and can adjust from there. None of this is set in stone.

I had 1mm toe out total and it was great. highly recommend, but of course suspension set up is a package deal so it depends on the rest of the set up.

LVDell

FYI....I ran between .5 and 1mm of toe out up front depending on the rest of the setup.

1mm of toe out per side is about 7.5' of toe-out. That's 15' of toe-out total, which is a boat load of toe-out. In fact, that's more than double GT3RS specs (0-3' per side). 1mm total toe-out seem closer to workable for sure. Personally, I would be a little nervous with 7.5' of toe-out per side (15' total) on my car as I drive it on the street as well.

As for the rear, 1.75MM is just over 13' of toe-in for the rear, which is a a common amount.

YMMV

SH//NC having negative toe out will make turn in so much better but be careful turning in too much : ). Mike

Thanks everyone for the feedback.

I had it up to ~85mph on the freeway today and it was a ***** cat; no wandering, no dartiness, no drama; the added turn in and more planted feeling is nice, even on street tires. We'll see.

That dash mounting bracket is sweet and I think it'd fit my 930 with little to no mods. Can you pls tell me where I can buy one?

Thanks!
