So I now have a lot of people involved at Lexus looking into getting my ISF correctly aligned. However whenever I ask for the alignment spec they just show me the sheet from the alignment rack and it's "ranges" (which by the way my car cannot even reach). So I'm trying to get them to work on the subframe to straighten things out.

Anyway. What are the exact specs for the ISF? For example "camber = -1.5" "caster = 8.0" "Toe = +.1" etc.

Anyone know? I want Lexus to make my car align like it was designed not get the dismissal that "It's with in spec".

In my opinion the range is too crazy wide for example the camber ranges from negative to POSITIVE! how can that even be considered i the same range?


Done ranting, some help please?

Thanks,
Andy

I don't know the exact spec you are looking for. Is the reason for this question of yours because of your car pulling to one side? If so, there is a thread that deals with that to get it within specs all the way around. If that is the case let me know and I will try to find that thread again.

Trust me, I have read all the threads here and on every other Lexus forum about the F pulling. I have had the car in for pulling 4 times in the last year to address this issue. I have already had the caster brackets installed on both sides, etc. for this issue.

The spec I am looking for is the one the car was designed to have. Engineers don't give a range for alignment they give a single number for each aspect of the alignment and a range for a car to go straight down the road in case there is damage or other uncontrollable factors that keep the car from being aligned.

Especially for a car like the F that has almost NO adjustability for alignment (certainly none for Camber) should have engineered specs for camber.

glad to see that you found what you were looking for.

As for the constant pulling, when you get your alignments are they able to get it within the tolerances? Here is what I was referring to about the constant pulling, these guys had problems getting the car into the tolerances with a typical alignment. Apparently they had to loosen the subframe bolts and adjust it that way.

Check post 45...it starts there. Not sure if you saw this before.

well after looking back at your links you have posted, looks like you have read that thread/post that I referred to. I couldn't open you link, but it looks like it should point to the same thread.

best of luck. Hope you get it worked out.
