Never heard about grip softner - What is it? Where can I buy some?
GRIP TYRE SOFTENER - YOUR #1 CHOICE IN THE WORLD!!
is the stuff, big in the states, would have thought its a worldwide product, I often buy it off ebay.
Again, where I can get these springs? Do I search for springs for coilovers? Are the springs brand-specific or any brand of spring will suit my coilovers? And what must I look besides spring rates? Length? Height of the spring?
Any brand, I use D Faulkner Springs Standard Springs
in the UK, eibach do them also but at twice the price. Coilover springs are generally 2.25" or 2.5" inside diameter, you will just need to specify the spring length and rating in lbs or nm.
I also have helper springs which are squshed right down with the weight of the car but keep the main spring in its place. 8" or 9" springs are typical. I run a 6" main and 4" helper on the front.
I run my car with aprox 2 - 2.5 degrees of negative camber at the front and back - I heard that as the 156 suspension is by double wishbones, negative camber can be achieved solely by lowering the car.... Have you used camber plates?
My track car is not an alfa, but the suspension setup is very similar, double front wishbone.
The lower arm pivot points (mount vs ball joint) want to be parallel under load, sometimes people lower too much, some cars can start to go positive camber under load, I don't know if the alfa does or not.
I used adjustable top arms to deal with the camber, and then heavily modified them to get up to 5 degree negative camber.
The rears are adjustable top links as well - this will give you an idea, although not for an alfa http://www.ebay.co.uk/sch/i.html?_nk...at=0&_from=R40
but somewhere like this with their hefty price tags may do something similar Suspension | Classic Alfa Romeo spare parts and accessories
Do you have the size of the bearings that fits to lower arms? Again, where did you buy them? It is a really nice idea for a track car, I just do not know if I can put any type of bearing or must I select an heavy-duty one....as they will be sumbitted to a lot of pressure... I have poly bushes in my lower arms.....never heard before of bearings in the place of bushings in the suspension arms!
FK Precision Wide Series Spherical Bearings - SummitRacing.com
, in the UK people often import the sphericals from the states, I had to.
Sphericals are needed in certain places, but my front lower arms were just standard bearings that a local race machine shop made up, a standard bearing being a round tube turning inside another tube, no ball bearings or anything complicated, (a bit like these PCI 8 PIECE Bronze Bearing Kit 92-95 Civic / 94-01 Integra - Pro Car Innovations - Performance Parts
) if you can find a decent machine shop, it will be a walk in the park for them, I simply took down my existing front lower arms and they fitted the bearings for me.
