I have a lot on my plate right now so this will have to be brief. I=E2=80=
=99m replying to Mike=E2=80=99s earlier post and not Jim=E2=80=99s mods.

 =C2=A0

In Mike Jones=E2=80=99 talk a few weeks ago at SUNI he described some of th=
e challenges that he, Kevin Beattie and the Rootes engineers encountered wh=
en they put the Tiger into production. He mentioned that they knew that the=
 rack position made anti-Ackerman an inevitable problem, but they were unde=
r a deadline to put the car into immediate production. They did design a MK=
2 version would have larger 14=E2=80=9Dwheels which could accommodate longe=
r steering arms to lessen the problem as well as the larger 3-puck Girling =
brake package used on the Cobras and Austin Martins on all corners. But by =
the time the Mk2 was produced these were eliminated and only Mike=E2=80=99s=
 relocation of the Panhard bar mount survived, chassis-wise.

 =C2=A0

So we all know the Tiger=E2=80=99s Ackerman is terrible. It also suffers fr=
om a complete lack of camber gain. And its bump steer is horrendous. (We=E2=
=80=99ve carefully measured all of them.) One discovery that prompted a chu=
ckle was that when the Tiger takes a set in a hard turn the bump steer is s=
o bad it actually corrects some of the Ackerman problems. I pointed this ou=
t to Mike and expected him to identify an engineer who came up with this en=
tirely creative band-aid but instead he said he was sure it was completely =
unintentional. That immediately let the air out of my balloon.

 =C2=A0

As far as aftermarket fixes, Dale=E2=80=99s numbers look great for ackerman=
, camber gain and bump steer. I=E2=80=99ve driven Tigers with Hokansen=E2=
=80=99s mod and they drive nice but I never have seen his numbers.

 =C2=A0

As far as mods to the stock suspension, the main problem for me is Camber g=
ain. When the chassis rolls it rotates the inside of the tire patches off t=
he pavement. Any real fix needs the ball joints to be an inch or two furthe=
r apart. The Tiger spindle weighs half what a Pinto=E2=80=99s does. It=E2=
=80=99s flimsy in comparison. We have seen enough flexing on the race track=
 that I have been scared to space the ball joints further apart. We built a=
 spaced a setup and did a one-day test with it at Willow and it worked but =
it now sits on the shelf due to my reluctance to take on more risk.=C2=A0 M=
G arms take a little of the problem away as does milling off the =E2=80=9Cf=
eet=E2=80=9D on the rack but the aftermarket solution of putting the rack u=
nder the motor addresses all those problems. I think Dale is still selling =
his replacement crossmember front suspension but I suspect they will now co=
st you more than $5K.

 =C2=A0

As to the electric power steering from Europe, I=E2=80=99ve installed and t=
ested it. It=E2=80=99s fine around town and on twisty roads however I can=
=E2=80=99t get enough caster into a Tiger to make it reasonable to use on t=
he open road. It has too much friction for our cars to overcome it and trac=
k straight on the highway. You have correct constantly. For an hour or two =
that=E2=80=99s OK. It=E2=80=99s so much work that an 8 or 10 hour cross cou=
ntry day became impossible for me. So it now also sets on a shelf in the ga=
rage. I=E2=80=99m expanding the garage.

I'm far from expert...maybe a layman open to experimenting lol=C2=A0

 =C2=A0

I think a lot of guys building Mustangs, Camaros etc still do the Shelby dr=

) when shimming for negative camber. That clearance becomes even less when =
you start looking at dropping the physical location of the UCA. So, the que=

Wonder if anyone has done it?

countersteering (what I think he meant).=C2=A0 I wrote a program to figure =

you get to pretty extreme steering angles, so on a big track it isn't reall=

ad on a really=20

tight course.=C2=A0 And because of the fulcrum pin issue, I NEVER go full l=

Yeah camber... why did the lowered a-arm trick seem to work back in the day=
 but isn't used anymore?=C2=A0 The GT-350s I have looked at still have it.=

I know it was bad for braking but so is initial negative camber?=20

Heavy steering, why I left my big stock steering wheel.=20

Gary, I think you nailed it, reverse Ackermann leads to some funky slip ang=
les and strangely heavy steering, particularly felt at low speeds...the fro=
nt tires are literally fighting each other. The fact we all typically add w=
ider wheels makes the steering even heavier (both contact patch to move aro=
und and scrub radius). Finally, maxing out caster with wedges (which I do) =
makes it even worse!=C2=A0=20

The longer MG steering arms help, I've found on cars I've driven so equippe=
d, but I haven't bothered to do on my car. Toe out changes the slip angle a=
nd also helps get the car to turn in, but I only go to toe out (1/4") when =
autocrossing, as toe out also is a great way to kill tires. Besides the poo=
r camber curve, Ackerman is another reason why I run as much negative cambe=
r as possible...if the outside wheel isn't technically aligned to the turn =
radius correctly, at least I can maximize the unaligned contact patch in ro=
ll lol. Funny thing, even the real experts I've read can't seem to agree on=
 "Ackermann", because there are so many other variables.=20

I don't know, outside of a custom solution like Dale's or Hokanson's front =
ends, of a real fix. I've just learned to live with heavy steering, but if =
it really is a problem, going to stock width wheels and smaller section wid=
th tires really makes a difference. The electric power steering solution ha=
s gotten to be a pretty easy=C2=A0deal, but that obviously does nothing to =
address the underlying geometry issues.=20

ip angles and strangely heavy steering, particularly felt at low speeds...t=
he front tires are literally fighting each other. The fact we all typically=
 add wider wheels makes the steering even heavier (both contact patch to mo=
ve around and scrub radius). Finally, maxing out caster with wedges (which =
I do) makes it even worse!&nbsp; </span></p></div><div><p class=3D"yiv71468=

r:black;">The longer MG steering arms help, I've found on cars I've driven =
so equipped, but I haven't bothered to do on my car. Toe out changes the sl=
ip angle and also helps get the car to turn in, but I only go to toe out (1=
/4") when autocrossing, as toe out also is a great way to kill tires. Besid=
es the poor camber curve, Ackerman is another reason why I run as much nega=
tive camber as possible...if the outside wheel isn't technically aligned to=
 the turn radius correctly, at least I can maximize the unaligned contact p=
atch in roll lol. Funny thing, even the real experts I've read can't seem t=

learned to live with heavy steering, but if it really is a problem, going t=
