Toe angles being off can also affect ride quality pretty strongly.

Car Analogy

A full suspension refresh would be all bushings, balljoints, tie rods, shocks. But I've never heard of anyone wearing out all these components in that mileage. Bushings usually die from aging rubber (combined with driving like it was meant to he driven), not from miles or over driving the car.

For bushings to cause ride quality problems they have to be practically falling apart. Cracked and a little worn won't do it. You would have alignment issues like described above first.

Worn balljoints and tie rods would have other noticeable symptoms before they deteriorated ride quality.

Thanks for your inputs!

Alignment isn't an issue. the car was just aligned after I put on the Ohlins DFV coilovers.

Btw the ride quality isn't downright terrible (there no clunks or anything).
It's just not as good as other s2000's I've been in and the family owned one I've driven many times, so that's why I thought it might just be a combination of bushing wear and wheel bearing & hub wear.
(It was slightly worse before I changed the shocks, so that helped a bit).

So that's why I am thinking of doing the refresh to get it up to par with what it would have been like new.

Since I don't see any other components that would contribute to chassis harshness.

I am wondering which route to go with.

Spoon Rubber Bushings
Mugen Rubber Bushings
Hardrace Rubber Bushings

Oem arms (seems excessive for the $)

So...Idk if its been answered yet.

Which bushings, specifically? Or all of them? You said "all the LCA bushings".

Front? Rear? And just the actual LCA...or are we talking rear toe arms also?

singhgugu

Well if I do a bushing refresh, I'd prolly just replace them all.

but last time I looked, a few of the front and rear LCA bushings seemed cracked/worn

ill have to check again to see exactly which ones.

ill see if I can get some pictures this weekend

Hard race rubber bushings on my ride, they work really well.

HR makes great stuff. It would be hard to pass up the OEM or Mugen bushings, though. The stock design is pretty nice.

I can attest to the comment about the soft top rattle. The car seems to ride so much better when the top is down LOL

Thanks again for the inputs!

Yeah I was thinking to go with Spoon, HR, or Mugen since it is an "upgrade from stock" and isolates NVH, but the decision is kinda tough.

Theres a lot of information on Poly and Spherical bushings.

From reading up & researching, it seems like this sums it up:
--Poly:
--the most consistent NVH and most upkeep with lube, so that's a no-go for me - out of the question

--Spherical bearings:
--super smooth on most bumps since there is no bind, and very tempting from all the reviews I have read. Some threads say it rattles a lot and some threads say a good set will ride way better than stock, so I am unsure.
(I am particularly curious about the Ballade Sports set of spherical bearings)

--Hard Rubber
There aren't not too many reviews of the harder rubber, so
--If Mugen/HR/Spoon are harder than oem (I read something like 85 vs 65 shore durometer ~ 30% increase - is it a linear scale?).
If that is true, wouldn't that mean like 30% more bind in the suspension, and something like a 30% higher effective spring rate.
This makes it seem like they would ride tougher than stock and transmit more thumps vs rattles.

I guess the decision is Spherical vs Hardened Rubber as a 90% DD 10% track.

I was set in stone with rubber, but some reviews in this site really claim that spherical shines on this car. I am curious for opinions.
