I find it strange that the springs would settle this much or that the set screws on all four sides are not set? Either way seems I need to pull a wheel and definitely raise it back up before installing a front splitter.

I know it's a bit late but finally got around to taking a picture of my front suspension and surprised it's set so low.

Wow!!! Show me some more pix of your car, I want to see the front to rear gap!!

For some reason, I cannot find the exact same tape measure used in the other picture?

OK, something is not right. The measurements below are P/S same as before. So the car hasn't settled more. Whew! The pictures w/o the tape measure are the D/S and measure 585mm/590mm. Now if the car was weighted shouldn't the D/S be higher or is that only during alignment? Either way looks like I need to pull some wheels and make some adjustments.

Do you happen to have a pic of your car to see how it looks?

Nevermind, just saw your pics after I posted. Your height is exactly what I'm looking for! Thanks for the pics

Yea those black 763s that he has in his delivery pics are tempting me...

Omasou, are you running spacers?

I'll have a set, but they have to be powdercoated before they go on my car.

There I have some Good News: You can adjust it without removing the wheels. Having arms like a Gibbon helps, but.

Nope, all stock.

How is this possible?

D/S (L) measures 585mm

P/S (R) measures 590mm

The body is slightly off, and whomever installed your suspension compensated for that, but it settled a bit more?

Still looks weird. Mine were spot on to the 32nd, with one being a bit higher than the other because I wanted the set-screw in the front.

EDIT: Oh wait, the lower one is the one with more threads showing??? OK, that's very weird.

Thanks for the pictures once again! Now I have something to work with this weekend to achieve your height. Would you happen to have a pic of your rear collar?

Hopefully the ends of the spring coils are firmly against the stops at top and bottom on both sides?

On the plus side, you need to wind them up, rather than down. So plenty of adjustment available...

Just got confirmation that the 10 strut top bolts that are different are in fact supposed to be different for installing the MPS, so I'll be doing that soon.

My question is; do you think it would matter, since the strut tower brace is there, if I take them all off at once, or do you think I should do them one at a time, torquing as I go?

There are a few in this thread w/some info. Don't forget to remove the stock cups.

There are a number of reasons why the collars may be set at different heights but still be correct for the car.

1. Springs are not high precision components. There are going to be manufacturing tolerances between components both in terms of length and elasticity. It’s unrealistic to expect two springs of this size to be within 1mm tolerance of each other when compressed under load.

2. The weight distribution of the car is not 25% each corner. There are static variances and dynamic variances with the latter affected by fuel load and occupant weight and seating position.

3. The height of one perch has an effect on the ride height of the diagonally opposite corner, even if the latter perch is not adjusted. For example, if you wind the back-left perch up, the front-right ride height will be slightly lowered.

The last factor is especially important and a good reason why, if you fit height adjustable coil-overs, you should spend some extra money and have the car corner balanced. The worst way to set the height of your coil-overs is to just count the threads and set each perch the same and say “that’s it, I’m done”. This is only the first step.

The second worst way to set the height of your coil-overs it to measure the ride height on each corner and try and get them all the same. I’ll give another example. Joe Blow finds the front-right corner is too low. He winds that perch up to bring it to the same height as his front-left. Then he measures the rear and finds the back-left is too low. He winds that perch up to bring it to the same height as the back-right. He goes back to the front and finds the front-right has “settled” some more. He repeats this cycle a few times over with smaller and smaller adjustments each time. What he doesn’t realise when he is finished is the car is now carrying a large percentage of its weight on the front-right and back-left wheels and the other two, despite riding at similar height are just dangling there with far less weight on them. As a result, his car turns in crisply in one direction but is slow and wallows when turning the other way.

If Joe knew beforehand what the relative corner weights were, then rather than raising the perch on the front-right wheel he might have lowered the perch on the back-left. Then to raise the ride height on the back-left he might lower the front-right. Say what? That sounds counter-intuitive because the front-right perch is going the opposite direction to what we originally anticipated. True but what is actually happening is the weight is progressively being shifted to the diagonally opposite wheels until the cross balance is even. Only when the cross balance is even will we get the results we expect. It’s a black art best entrusted to experts. But the end result is the car will turn equally well in both directions and appear level although the perch heights may be quite dissimilar.

Your car could have been set up correctly. Or it could be effed up by a lazy technician. If it hasn’t been corner balanced, I suggest getting it done then don’t look at the spring perches again or it will mess with your head.

Visual, I hope you don't mind me being all over your thread but if you do please let me know.

Awesome! That's all I need and thanks for the tip about the rear stock cups. I've done 3 E9X's coilovers before but never on a F chassis, to be honest though they look exactly the same.

Such a weird thing with this car, the front kind of looks right, but when I reach in with my fingers there is obviously more gap there, so tomorrow I'm going to lower it a bit more and take some additional pix. Good times, good times!

If the car is on it's wheels, I don't see why not? But one at a time also wounds good.

As to the bolts, they gave to the gasket for fitting the MPS to an M2C, so...

Yeah, I've spoken to a few people and I don't think it matters either way.

My thing is, I'm wondering why I have to replace them anyway, seems weird to me, and there are so many, I can't imagine having an issue with them coming loose.

Yes, they made a few mistakes with the shorter 12-pt nuts, and the gaskets, but they are willing to refund my money. Sucks that I have to pay shipping back though, not my fault.
