Diy alignment

So I’ve driven it for a bit on the new bushings/springs/shocks. The ride is improved for sure, superformance uprated springs and hard bushings. Suspension feel is quite subjective, so for me it could be a little firmer, and has a bit of travel but expect that’s about right for vintage Ferrari. Not bottoming out so far so that’s good. Anyhoo we were discussing alignment in the other thread so I thought I’d start a new one and share.

More images from the shop manual. Again like the other pics I posted in the bushing thread, slightly positive front chamber..
And again supposed to be measured loaded with 2 persons and 20kg in the boot. It doesn’t mention how heavy the 2 persons are supposed to be. So I assumed me in the driver seat and a slim lady in the passenger.

Here are the pages from the other thread that I posed about the ‘loaded’ description in the manual

So 50 lb bag of rice and my helper in the drivers seat and a 50 lb bag of rice and bottles of water in the passenger. 20 kg of flour in the boot.

My work sheet. Got to use some math and trigonometry, man first time I thought about trigonometry in a while but turns out I could work everything out with a little thought.
Readings between loaded and empty just with 3/4 tank of gas weren’t that different.
So maybe there no reason to do it loaded? The drive height did change tho obviously.

In the end I accepted essentially 0 camber instead of slight positive in the front, 0 toe.

Caster was ok, just over 4 degrees.

Rear 3.5mm total toe-in and about -7 degrees camber in the rear.

I couldn’t adjust anymore as I ran out of shims!!!

Will drive it like this until I get more shims but I suspect it’ll drive fine... will report back.

The controversial 10-30 sec positive camber (or 0.17 to 0.5 degrees) actually isn’t very much...
but in the end I sort of left it half ass at 0 ish

Oh and the mm toe value are for stock 14” wheels, altho practically there’s not a huge difference (I think only 0.005 degrees less for the same 1mm on an 18” wheel)
(And sorry -0.7 degrees camber in rear not -7)

Well just drove about 80km. Felt ok. Remeasured the camber still 0 in front in the rear it’s -1.1 degrees on the drivers and -1 on passenger side. So takes a bit to settle.

Oh good point, I had looked at my owner’s manual and thought that numbers/loading were the same. I just checked again and the front camber is 0 to+20 sec, which makes me feel better.
I’m on stock 205/70 14 xwx.
And I don’t think I’m lowered but have superformance uprated springs and hard bushing I just but in.

Those are called smart stings, easily to check/realign. Some shops use them. Can be used at the track as well. Lasers (as some who often uses them as work) are great but they’re user dependent. Quite convenient for me to realign between track days if I don’t like something. (Altho I’m not tracking the 308, I have my Andial 993turbo and first gen nsx for that [emoji846])

But it’s fun! You know that from turning your wrenches!

For the toe in I’m using those strings (see above). For camber, you can buy a variety of camber gauges but you really only need a couple of magnetic electronic levels from the hardware store. You need a flat surface (like your brake rotor if the surface is smooth - with your second gauge can make sure you have your first gauge pointed vertically - or make a straight edge that contacts the rim edge to place your levels on). Hubstands are the best tho, mine are porsche bolt pattern so couldn’t use them on the 308, but might make an adapter. They make adjusting so easy (especially if you have dog bones for a-arms)

Oh and just like I mentioned a few post up, after you drive for a bit, you might find your alignment has changed. Would never know if you didn’t/couldn’t check.

And caster needs a little calculating if you don’t remember the constant. Need to check your camber with your wheel turned 20 degrees in and out (can use the smartstrings and trigonometry to get 20 degrees). Then there’s a formula but if you don’t want to calculate it out, the constant if you use 20 degrees is 1.43. So take the difference in camber and multiply by 1.43 to get the caster.
