Next gotcha, the oem sidemounts bolts are flanged M12x120 1.5 gr 10.9, the solid mounts need flanged M12x85-90 1.5 gr 10.9

For future reference, there is no dimensional difference between the '95/2 alumium castings and the RS parts that I replaced them w/. The diifference is all in the bushes.

The last gotcha w/ the solid side mounts is that the stock 4x M12x1.5x110 gr10.9 bolts are too long, maybe they would be ok if a tilt kit was also installed.
M12x1.5x85-90 is needed, turns out that the KT arm bolt is M12x1.5x90 gr10.9 and works fine.

As far as I can see the tilt kit would be more appropriate for much higher hp than I have.
And
I didn't like the way that the front cross member fits when used w/ a tilt kit
here's the issue w/ tilt

and this can be done w/o dropping the engine/trans

Do you have a kinematic toe gauge? If so, have you measured yours?

I should have said it better. Without the adjustable arms and with that ride height (like mine), I don't think you can get enough range with just the eccentric. The monoballs vs rubber bushings don't really make a difference in the adjustable range.

front is getting, upgraded mono ball/camber plates, RS A arm bushings & springs to match the back.

Bill,
Which kinematic toe gauge do you have? Is it the Autometrics one? That's the one I have. I've been experimenting with different settings and have finally found a sweet spot (I hope). I have it at drop dead center (by the hole). I could never get there without the tilt kit.

As far as I can see, I want to minimize KT, w/ monoballs that's a done deal, there is no KT. W/ The RS and normal use the same KT arm/bush so all you can do is minimize it's effect.
I am certainly looking for all the feedback I can get on this subject. But it appears that the usual suspects are holding their cards close to their vests.

Bill,
Here is what the tool looks like:
http://www.autometricsmotorsports.co...ts/ktt/ktt.jpg
You can see the hole at close to 4.5 on the measurement. Before the tilt kit, I could barely get a reading (over 8). Now I can get down to 1 on the scale.

George- is that because you're extremely low or something?

I have to admit that my understanding of KT is very vague. The final step in this whole process is an full align/corner balance by someone that knows what they are doing.
