LSS vs. Base suspension-finally, some answers

There's been a lot of talk and debate about the ride quality difference between the base suspension and the LSS. Reports have come in about how "numb" the feel is in driving the LSS, and how some owners much prefer the feel of the base suspension on the street vs. the sport suspension. Some have suspected the reasons, but I might be the first to have gathered empirical evidence on all of the possibilities.

I started with a base car, enjoyed it immensely, converted it to the sport suspension, and raced it in that configeration. The car did indeed feel numb with the LSS and wider fronts. But was it the suspension or the wheels/tires?

Well, my 2nd Elise came with LSS/LSD, and it felt numb just like the base car converted. I added DA shocks and did some radical alignment work, and the car was number than ever. It's lightning fast on course, incredible. But on the street-just not as much fun.

I recently bought Stan's old base rims and put AD07s on them. I loaded them on the LSS car tonight. Am I the first to put base rims on a LSS car? Maybe. Anyway, the feel is BACK! I can't believe how much fun it was to drive on the street again. I have a very, very aggressive suspension setup, and the car was pretty loose, took me a couple of miles to get used to it, but damn it was responsive and communicative! Banana time!:nanner2: Make it a double!:nanner: :nanner:

Conclusion: Tire and wheel create the feel, not the shocks or springs. I have driven every configeration of tire/wheel/suspension out there, and the base wheel/AD07 on any config will give you that great responsive feel. If you have only driven the LSS car on the very numb 48s, you owe it to yourself to pick up a set of base rims (very affordable used) load AD07s and use them on the street. Save those 48s for on-course experiences. As an added bonus, you'll get 12K miles from a set of AD07s. :)

Jer,
That's exc. to hear your perspective having experienced variations. I've often thought a lot of the people complaining of the harsh ride on the street were doing themselves a disservice by having sport suspension instead of standard.

From early on LA show 2004 the Lotus engineers were trying to encourage getting standard suspension to make the car better all rounder.

Since I sold my wing mine hauls groceries, and 50 pound sack of bird feed fits nicely in the boot btw!

Well I'm thrilled to have a lightning fast car on course, and still be able to enjoy daily driving! LSS cars feel great with the base wheels, every bit as good as base cars with those wheels.

Based on driving Jacob's car in an autox setting, which has Penske shocks and AD07 tires, I would agree with your findings. Perhaps it is the skinny front tire? The excellent steering feel is maintained, while being very composed. Very little body roll and excellent balance. There is a bit more drama with the base suspension however.

I have noted a number of excellent drivers thinking that the base suspension is more fun on the street.

THe skinny profile up front makes a ton of difference. For the last two months I ran the base AD07s on LSS rims. Vey numb, but not as bad as the 48s. Tonight I reloaded those tires onto the base rims and voila! a world of difference. :)

Are there any tires that will work well on the street on LSS rims? The 175 is too small for the 6.5 inch rims and there is no AD07 in a 185 or 195.
Actually, many people have mounted the 175 on the 6.5 inch rims (as Surferjet did - see two posts up). Yokohama will tell you that the 175 is good to a 6 inch rim, but it has no problem going that extra 0.5 inch.

Yes, although Michelin seems to be a dirty word here, the Michelin Pilot Exalto PE2 is an excellent performer for street driving. I put them on my base suspension elise on european exige wheels, felt great. Then I put them (wheels and tires) on my exige, and the car is great!:nanner: :nanner: :nanner: Quiter, great feel, and the performance is better than you would need for any street conditions. They will probably last at least 25,000 miles and stay stickey the whole time. If I ever race, I have the Ao48's that came on the car. :nanner2: :nanner2: :nanner2:

As for comparisons between the AD07s on the wider rims, it feels fine, much better than the 48s. But on the narrower rims it feels so much more alive!

Boy! Makes me glad I bought the car with "touring" wheels!rotfl

Thanks Jer for the great info. I had been looking for a used car with LSS.

If having LSS gives you poorer steering feel and control I would rather save some $$$ and go with the standard suspension.
cheers

You're welcome!!

Unless you're racing the car, get the base suspension. You'll have a great time, save a few $$, and never miss it.

If you plan to track her, get LSS and then pick up some base rims for the street. You could then use the LSS rims for track-dedicated tires.

I think the car feels the best on the street with LSS wheels (or equivilent weight) and street tires, Hankook RS-2s, Goodyear F1s etc. I don't like the way the car turns in with the heavier standard wheels.

And if going fast is not important at all, and you want it to feel even more alive.. get the tires found on this:

Numbness GONE. The car will really feel on edge.

Reports have come in about how "numb" the feel is in driving the LSS, and how some owners much prefer the feel of the base suspension on the street vs. the sport suspension.


I would beg to differ on that. To the contrary, it's the standard-suspended car that has a slightly less positive response on turn-in and tracking through the turn. I went from a standard car right into a Sport Suspended car and noticed an immediate difference. There is also substantially more body roll on the standard car. None of this is a bad thing but the LSS cars do steer quicker and require slightly more input pressure on the steering wheel, track better and yes, ride quality is definitely more harsh (but worth it).
