I've lowered the track pack shocks as low as the threads allow on 2 of the wheels to even out the ride height, however I'd like to go just a bit lower still.

Is there any way I can lower the suspension another 5-10mm?

Front driver - maxed out (fully lowered)
Front passenger - 5 turns left
Rear driver - 5 turns left
Rear passenger - maxed out (fully lowered)

thanks!

Ara, are you having any trouble with bottoming your splitter? I was driving about 30mph on a slightly bumpy road last weekend and heard a large BANG from the front end... so bad I pulled over. Luckily, no damage... and I'm at the stock ride height.

Ara,

I respectfully suggest that you get your car corner balanced, the height checked (measured) properly and then aligned....I've got to believe that you are already running way too low for "good handling". Without adjustments to the steering rack, you don't want to be any lower than 115 mm (if even that low) up front, measured from the chassis reference points specified by Lotus.

Just my 2 cents and probably worth less. :)

+1 on getting it corner balanced, ride height checked and getting a complete alignment

keep us posted

Yes...I have to make it 3 on the corner balancing and alignment. I put the Sachs suspension on my car and I cant believe the difference after the alignment and corner balancing. It is set up at 130MM.

I thought the car handled great before...now it is almost unreal.

Lotus is adamant that it is extremely dangerous to have too low of a ride hight.

You will be on the bump stops too much of the time and then your wishbones will have to bend to allow some compliance:crazyeyes

Very bad things will start to happen at that point.

I agree that at some point you'll do bad things to components themselves, but getting down onto the bump stops is just a plain bad thing that you don't want happening. Remember that the instant you touch the stop your car will no longer be compliant to any real extent and it will lever itself over. You'll get radical and very unpleasant handling surprises when you get on the stops. Ask me how I know :)

I have track pack too.
You are to low.
Any movement up or down and you need to do an alignment. To get max track handling (or handling in general) do a corner balance. As in you in the car when doing it.

I am not sure but I think 120mm front and 130mm rear is recommended, I am not sure how much under that is bad, I would talk to an expert...
Actually, Lotus recommends 120mm front and rear in their Track Pack setup instructions with the caveat that the front should never be higher than the rear. You can probably go a bit lower in the front than 120mm before introducing too much bump steer and other bad things. ;)

Curious to know who you would recommend to do the work in the Ventura County area, if anyone? TIA

How about Carl? He's pretty close to most of Ventura.

It seems odd that Lotus would recommend a level ride height with the trackpack and 10mm height difference with the LSS. Doesn't leveling the car defeat the raked goemetry? I would think that would underweight the front and change the roll center? THe most experienced mechanics for our cars have all told me to have the rear up about 5mm higher.

The service manual (at least the version I have) shows the base and sport heights both being level front to rear.

No problem, Jack, thanks.

Carl, cool, thanks - I will find out where he works by checking the forum.

Carl is not in the business of doing alignments. :thwack:

What does Lotus know....;)

I believe in rake.... and have mine set up that way. :shift:

BTW, I'm unaware of a 10 mmm Lotus recommended rake for the LSS.

My mistake about Carl and the 10mm rake recommendation. Lucent and Allen did recommend raising the rear though by 6mm - not a lot, but I'm not sure why the like that spec.

I figured so many cars had been set up by Carl I thought he was kind of in the biz. He's such a mysterious guy.

i do set up lotus's ride height corner balence and alignment. because i never could find anyone that would take the time to do it right it takes 3-5hrs. the trick is to get the cross weights 50/50 and the ride height to less than 1mm difference side to side. When i changed the springs on my car i set it, last week i rechecked it and the springs had setteled and the cross weights were off by 20lbs.
My car is now set @ 115 and 120 and 1077lbs LF/rr and 1077lbs RF/LR cross with 160bs of weight in the drivers seat. send me a email if you need help

I've read a little bit about bump steer, but am not sure exactly what it is.


Ara, are you having any trouble with bottoming your splitter? I was driving about 30mph on a slightly bumpy road last weekend and heard a large BANG from the front end... so bad I pulled over. Luckily, no damage... and I'm at the stock ride height.
no, I haven't scrapped the splitter going in and out of driveways or speedbumps with the lowered height. I haven't bottomed out either.

I totally agree with you, Jack. I just haven't made the time to go have it done. Not very accurate, but the fronts have a finger gap from the top of the tire to the fender. The rears have maybe 1.5 to 2. It's tought getting an accurate measurement of ride height from under the car. Oh another way I measured was from the ground to the fender (center of tire) forgot what those were. I can measure tomorrow.
