Right...check out my new thread about F/R track.

The Evo's have equal front and rear tracks which makes it that much stranger to me that someone would add spacers in the rear.

Bump for a great thread.

My work has a nice alignment machine so I'll be posting what my car is set at and how it feels shortly.

Whiteline has updated their alignment specs on their site.

They now list 2.0 camber on the front for full race. There is a pdf you can download with all the specs.

I looked last night and found my old specs from when Darrin at west end did my car for me (it felt great after that)

Front:

Camber (left) -0.8 (right) -0.8
Caster (Left) 1.25 (right) 1.25
Toe out (1/16")



Rear:

Camber (left) -0.75 (right) -0.75
Toe In 1/32 "

Holy cr@p! I did the alignment last night and I set my front camber to negative 1.4 degrees on each side and the toe to 1 degree positive on each side. (Rear camber is negative 0.8 degrees and rear toe is 0.8 degrees negative). MAN what a difference. The car is soooo damn responsive now - the steering wheel feels like its on a hair trigger, you turn it and the car leaps to the direction you turn and DAMN the difference in corners was impressive. You just turn in, nail it, and the car turns like a friggin rollercoaster car on a track. Its awsome. Those whileline sports level specs are definitely good specs.

Great to hear. I think the alignment being of on this car is why people have handling problems. If everyone invested in a proper alignment, are cars are more likely to smoke to competition.

:wink:

Be careful on a lot of toe out though, your tires will wear much quicker.

My alignment was in factory specs before (actually a little more aggressive than factory specs). but that extra camber up front seemed to make a huge difference.

The toe is probably what caused it to be so much more responsive. The extra negative camber should've worked out some understeer and provided more grip...

I had some info in my head a while and with some posts from other threads recently, I think I have a good enough grasp to share my view.

Front and rear track to adjust handling.
When I installed my teins, I also did my 25mm rear spacer atthe same time. At the time I thought the 25 mm spacer, made the front and rear track the same. The lookedclose visualy, but recently someone found they make the track 10 m wider. This doesn't sound like much, but from my experience it really effects the car.

http://alltrac.net/phpBB2/viewtopic.php?t=9661

I had a 8mm spacer that I bought to make the fronts look better since they were so tucked, even thought it didn't help my 17x7 40ets much, it did change handling a bit.

At first with just the 25 mm spacer the car handled well. There was minor push going into a turn, nuetral middle turn and slight oversteer on exit.

I tried driving the car with the 8 mm spacer on both fron and rear.
On the rear the car had simular characterstics to w/o the spacer but I had to turn up the rear struts to maintsain the slight oversteer on exit.

Instaling the 8 mm spacer on the front made the car scary. It made the car into point and go. I took some turns so much faster that it firghtened me cause I was used to being at the end of my limits at that point but now I still had grip. I however didn't notice the oversteer qualities much cause the car seemed to rely more on hte fronts to do the work and dragged me around.

I am not sure if a 5 mm spacer would be better for the sake of making the tracks even or the 8mm spacer since the front track is slightly wider than the rear. Maybe the best way to test is someone with 20mm rear spacers to test even track and then adding spacer on the front to see if it improves handling or not.

I think I will try adding my 25mm H&R spacers to the FRONT with no spacers in the rear and see how that feels.

I am still of the opinion that increasing the rear track does nothing but add understeer.

That is a good point there Cold-Iron. I added the rear 25mm H&R's just for the looks. I noticed the car didnt turn in as sharp, but the car felt more stable so to speak at decent speed. Be interesting to see what happens when the spacers are up at the front though.

Cheers

When you change the front offset you change the scrub radius, which will cause toe in or toe out on cornering depending on whether you move the centerline out or in. Thats probably why the turn in felt more aggressive on the front - its the same effect I got when I set my toe out a while back.
