Suspensions and stearing setups

[matt mead]

well her is my 3 cents on the above topic.....

I have spent the last 3-4 months trying to find a setup that works for me... i still havent found that setup but im coming very close....

current setup:

Front:
-Custom Coilovers, Toicko HTS insert, Koni coilvoer kit, Ebiach 6.2kg spring
-30mm RCAS
-Stock Swaybars
-Longer control arms
-Brand new ball joint and bushings
-T3 tension rods
-Cusco Camber tops

Rear:
-Kyb AGX 8 Way adjustable
-3.8kg Springs

Tyres:

195/50/r15 toyo r888

but all this has worked with

advan hf road tyres aswell

So lets get onto your problem

Ok ae86 are know to understeer, its almost impossable to make an ae86 not understeer at all.... but your seems like your car has some major problems... and it has nothing to do with your lsd, as your lsd is controlled by your driving style....

For suspension to work evertyhing need to be matched and worked together..... and before you start changing your spring rates and stuff like that i think you should look at cheaper alternatives such as tyre pressures, damper settings, then wheel alignment settings...

Tyre Pressure:

The higher your tyre pressure the less the tyre will flex and the less heat your tyre will obtain and threfore affecting the grip... Also the less the tyre flexs the stiffer the tyre stays meaning less surface area of the tyre will be touching the ground... therefore affect your grip..

with normal road tyres, you should be running around 30psi in all tyres, unless you want to drift and in that case you should run more in the rear therefore affecting the balance of the car..(cause rear end to want to slide)

Damper Setup:

(THIS IS HOW SUSPENSION GENREALLY WORKS YOU NEED TO FIND OUt WHAT SUITS YOUR DRIVING)

When on the street i run my fronts on 35/45 (where 45 is full hard and 0 is full soft) and i run my rear on 5/8 (where 8 is full hard and 0 is full soft)this is for a grip setup and if i want to drift i jsu tmake the rear dampers harder like 7/8 and bump the rear tyre pressure up alittle more..

Front:

Full hard: will make the car understeer as shocks can not absore alll the bumps in the road causing the car to skip and understeer

Full soft: will cause large amounts of body roll .causing under steer and jsut gay driving feel anyway

i think the best way to counter your problem is to set your front to the middle of there setup range, then slightly adjust it harder and till u find somethign that works

Rear:

Full hard: will cause oversteer as shocks can not absore alll the bumps in the road causing the car to skip and oversteer

Full Soft: will cause large amounts of body roll causing gay driving feel anyway and wont be fast

U need to do the same with this as the front, but remeber your rear shock setup for grip will always be lower then your front setup as there is less weight in the rear of the car.... but i think you should focus on the front of the car first.....

Also do you have RCA's(roll center adjusters) ???????

I think you should try both of these methods first... and see if that works and then ill post some more info up later.....
