Camber Adjustments?

[NYCQDude]

OK, I have Espelir lowering springs being delivered next week and want to have them installed along with a brake upgrade kit. On a '97 Q45 the Espelirs are said to drop the car around 1 1/4" in the rear and around 1 1/2 to 1 3/4" in the front. Haven't got my wheels yet, but didn't want to be too dramatic (don't want to go full blown VIP, just update/upgrade performance and looks to some extent). Was considering either 17 or 18" Eurolines. Most are telling me go 18 or I will be disappointed.

What is most important to me is getting a good alignment. Will I have to adjust the camber now no matter what size wheels I go with just because I am getting a fair drop with the Espelirs? Or will it depend more on the size/width of the wheels? I am really not knowledgeable about wheel swapping and camber adjustments so please forgive me

So please, any and all advice is much welcomed! Thanks for reading...

1" of lowering increases negative camber by ~ 0.83 degrees. There are no front camber adjustments on 90-01 Q45, The oem rear adjustments usually have less than +0.5 degrees of range.

Considering tire wear, braking and handling the worst thing one can do is lower body height by more than 0.75>1.00".

Thanks QTech.

I thought that lowering the vehicle would improve steering and braking (lower center of gravity is good no?). The springs I ended up getting are Espelirs because I tried in vain to get my hands on Eibachs (which lower 1"). The Espelirs may lower the front as much as 1.75" and rear as much as 1.25" from what the spring specs list. I know they sell rubber "extenders" which are supposed to add and inch, but then I figured they would defeat the purpose of getting a lower ride.

Now I am up in the air about even installing the springs! I wasn't trying to do it to be VIP'd out just for better handling and braking but if you tell me these will suffer I'm back to stock?

I value and appreciate your advice QTech, but please elaborate a bit more for and against lowering

In a 4 wheeled vehicle the treadwidth and wheelbase modulate the weightransfer vs center of gravity. Thus a few less center of gravity inches are almost meaningless in changing the weight transfer.
1-2% [of 1500 lbs] is not a significant chnge on tires............maintaining best camber is much more important.
Anything less or greater than 0.00 camber [when front is compressed] reduces braking effectiveness

I did realize that of course which is why I wanted to upgrade to wider wheels/tires (stock is only 215 and I was figuring on going to 225-235 with 17" rims) along with the springs - just once I saw how much of a drop I was dealing with once installed. If I understand correctly, the drop will cause a negative camber yes? I thought having a negative camber was better for cornering as the natural tendency for four wheeled vehicles during cornering is for slight positive tire cambering and loss of contact (more severe depending on the speed of the turn). Lowering the vehicle should help reduce the positive camber effect of the tires no?

As for braking, I had slotted/drilled rotors and ceramic pads delivered last week and had planned to swap them along with SS brake lines and the springs all in one go...
