Just wondered if anyone could provide the alignment specs for 6 speed CL-S. I know that camber and caster is fixed on the TL-S, but I wonder if anyone knows whether the manual CL-S has any adjustability with regard to C & C? Also, if anyone could provide the specs that would be great. In the TL-S when you get a 4 wheel alignment they are essentially adjusting toe. Thanks in advance for any help...

TCM 01 CL-S

I have alignment sheets for an 01-03 CL-S, 99-03 TL-S and I think an 04-06 TL. From what I remember, there was no option on the alignment machine for a manual CL, just the year and 3.2CL or 3.2CL Type S .

If you want I can find my CL-S alignment sheet or for the TLs.

I would be grateful if you could post both...

Which TL? 99-03 or 04+ tl?

01-03 CL Type S alignment print out.

Ignore the red circle, that was for another thread.

I hope thats what you were looking for.

Many thanks for that! So, it looks like the CL-S has adjustment for camber but not caster? The TL-S I'm pretty sure is fixed for both C&C. It is interesting that your "current measurements" for rear camber and toe are different from left to right side. One of my reasons for wanting this info was to see if there is anything inherent in the setup that accounts for why Acura specs more psi in the front tires than rear (I think manual CL-S is 35/32 psi and TL-S in 32/32). You have a slightly more negative camber and less toe than I have. This is generally advantageous for good handling and might contribute to the recommendation for higher pressures in the CL-S. Yours is a 6 speed?...

I have an A/T. I've always put 32/32 cold in my car, I believe thats what I must have originally read on the door, I'll check tomorrow.

I just double checked my 99-03 TL-S print out to my 01-03 CL Type S print out and the recommended specs are exactly the same. The reason I have a 99-03 print out is because my mechanic knew that the specs were the same and used the TL-S print out instead of CL-S for whatever reason.

All my recent print outs were before I lowered the car for the record.

Yeah, the 2nd Gen TL-S A/T is 32/32. Pretty sure the manual CL-S is 35/32. I suspect part of the reason for that is that the manufacturer expects the buyer of the 6 speed to be more sport oriented... Your 01-03 CL Type S print out doesn't specify A/T or manual?...

Only toe-in and caster are adjustable on the CL 3.2-camber is fixed. According to the CL Service manual: Caster 2 degrees 48 minutes +/- 1 degree; Camber front 0 degrees, 00 minutes +/- 1 degree, Camber rear -0 degrees 30 minutes +/- 1 degree; Toe-in front 0 +/-2 mm, rear 2 +/-2 mm. The turning angle is different between the Type S and Type P because the Type S has a lower steering ratio (2.8 turns lock to lock) than the Type P (3.2 turns lock to lock). The shop manual also calls for 32 psi front and rear for both Type S and Type P models-no differentiation six-speeds and automatics.

Thanks, dhorman, for your help. I guess I mistakenly thought the 6 speed CL-S spec'd 35/32. The alignment specs that you've given for the CL are slightly different than my TL-S with the CL having a bit less camber (0.0 vs. 0.2), which is a slightly sportier setup. Not much difference though and probably doesn't account for much. Thanks again...

As I said further up in this thread, I'm trying to figure how the CL/TL can perform best with 32/32 front/rear pressures when our cars are FWD with a 61/39 weight bias. I've experimented with all kinds of pressures and I do think that something close to the recommended 32/32 works best - I just don't understand why. With FWD and such a nose heavy car the slip angles should be much higher in the front than in back. Increasing pressure in the front tires could offset some of this and would seem to make sense on paper, but in practice I find handling is better at 32/32 or maybe 33/32 at most. Any comments?...

TCM 01 CL-S

Maybe the heat caused by the additional weight on the front as well as having to accelerate and turn on the same pair of tires causes the air in the front tires to expand more and end up at a higher hot air pressure than the rears.

dug-mac

Yeah, that is a good point and I'm sure all that is true. I've never really checked my tires hot, so that might be a good place to start. It is not uncommon for FWD cars to spec higher pressures up front, but many also don't recommend that - for example my old Maxima wanted 29/29. In general 32/32 is a fairly stiff setup (though many on these boards run much higher). A recent test in C&D of the new Vette shows that they are specing 30/30, and this for a car running 40 and 35 series tires...
