This was brought up in 2006 and Lamborghini of Dallas and a few others were mentioned. Time to bring it up again...

  • What is a good shop to mount and balance tires?
  • If not the same shop, and other than the internet, any suggestions for great prices locally on tires? (Probably sticking with the Lotus specific Yokos).
  • Any suggestions on shops for street-centric alignment?
Thanks.

I just took mine to PST Performance Speed Tech, at MSR-Cresson, on a Friday before 2 day track event last year. The fitted the Lotus track brace,reset the toe and did complete alignment.

I am assuming that street centric means don;t take out all the shims, nor set it p for auto-x with a bunch of front toe out.

I would be careful about where you bring it for alignment.
Many shops will not be too interested in doing what you want.
For instance when I brought mine in, he said "Well we will need to adjust the camber"
Me> "Why what is it at now?"
AG> ~1.0 degree each side.
ME> "That's where I want it"
AG> "No that is all wrong, you need +1 on the crowned road edge and +0.5 on the center"
...
AG> "Toe is all wrong"
ME> What''s it at?"
AG> "0.5mm out/side"
Me> Should be 0.25mm/side"
AG> No should be in 0.5mm/side

But he was very good though and set it up as per what I wanted.

I brought along 7 bags of cement to load the car for me and 1/2 a passenger.
You will want the ride height set before you align, and loaded for yourself (and what ever is appropriate for a passenger).

Here are some settings:
Holmz>
Camber // Castor // Toe
F-LHS -0.8 // 6mm // 0.25 out/side
F-RHS -1.1 // 6mm // 0.25 out
R-LHS -2.5 // ? // 2.5 in
R-RHS -2.5 // ? // 2.5 in

So the front caster of 6mm - how the hell does one figure out what 6mm is in degrees?
He moved the tyre ~30 degrees back and forth to get the 6mm from the gauge.
Would like to know what it means though, but at least it is even.

WP:
Take all camber shims out. Will give you
Front = -1.7 degrees
Rear = -2.5 degrees
I wanted a little more tyre contact in the wet so only took one of the two shims out of the front and both out of the rear.
Front - Toe Out 0.5mm overall
Rear - Toe in 2mm per side.

=========

You will want to make sure that they either align it to Lotus specs or your specs, and not to standard car specs.
Keeping the shims where they are at would likely be the best place to start- assuming that it is close to OEM.

If you do a lot of freeway then maybe 1.5mm toe-in on the rear per side, otherwise 2, or 2.5.

Write down where they set it.
If you have issues then it will be easier to know what to change.

The tire shop will:
1) Over fill your tires
2) Use an impact wrench
Stay there and bring your own torque wrench - in the long run it is worth it.
3) Make sure they jack it correctly (Another good reason to stick around)

another endorsement for PST - they worked on our lotus - installed tires, bled brakes, installed RTD brace, alignment. They are familiar with the car and do a nice careful job. The only bitch is that it is in Cresson, but hey you can watch the track and there is a Sonic close by.

Ruf has also worked on a few of them.
PST is top notch though.
