Ignore my post - I saw MassMini's response. I must be getting sun fever.

Please ignore my post. I must be getting sun fever. My appologies for the mix-up.

Impressions of the FSDs: Broken pavement and slightly raised manhole covers now cause a “thump” rather than the crashing sound/sensation with the stock struts. Washboard surfaces like a road that has been ribbed in preparation for repaving used to make the whole car shake – now it’s remarkably quiet and composed. Deep potholes are taken slightly better but not a huge difference here. High speed cornering is about the same. Highway tracking seems a bit better. Overall they have provided a measure of comfort gain I was looking for. Still likely to go with non runflats when the originals wear out.[Emphasis added.]

Maybe the ultimate ride harshness solution would be Koni FSDs & non-runflat tires in 16 inch size????
I did both -- put on FSDs, as well as non-runflats (215-45/17). *MASSIVE* difference. I think it's worth making both changes. I didn't get to drive the car a whole lot between putting the FSDs on and putting the non runflats on, but my impression is that the FSDs make the most difference on potholes, bumps, bad roads etc. with the improvement on smooth roads being more subtle, while putting on the non runflats softened out the ride over smooth roads as well.

I agree with MrT-Man's description. The greatest effect of the FSDs is in handling road bumps and potholes, and that includes expansion joints. The FSDs greatly reduce the sharpness of the jolt when you hit a bump or pothole. They should give you a very nice improvement for expansion joints. An added bonus is that the car handles better while going over bumps and road imperfections.

Would you say that the FSDs solved the ride bump that occurs when you go over an expansion joint that has "shifted" (more likely, it was installed wrong in the first place, but that is another matter) to the degree that the joint creates about a 3/4" - 1" bump on an otherwise smooth road? There are a number these joints in my neck of the woods and that is the only complaint that remains for me. The tire swap has made the expansion joint bumps tolerable; but if it is possible, I would like to have that become a non-issue too.

I had KONI FSDs installed w/ Hsport springs by Central Coast Coopers in Oxnard, CA on Saturday and had the wheels aligned today at EF1 Motorsports in Signal Hill, CA.
This is the best mod I have done so far (..OK maybe tied with the 15% pulley). The car feels more like a junior BMW M3 now, it is no longer harsh over uneven roads and handles significiantly better.
If you want more info - I can't stop talking about the FSDs send me a PM and I'll give you my phone #

My OEM struts will EOL ASAP so SYLA POS Delphis I'm going FSD & JCW.

I mean it's not going to turn the Mini into a Buick, but overall with both changes the ride went from being crazy harsh to very satisfactory -- much more akin to what a typical sporty car is like.
). But what I am most interested in is being able to tune the MINI's suspension into something that is the best of both worlds - excellent handling without ride harshness. I was able to do that in a past lifetime with a GTI; I would like to repeat the experience with the MINI. It really sounds like the last step is to add the FSDs. Any idea who has the best price on a set of FSDs?

Presumably your alignment was set to stock specs for Toe and Camber?
Front camber -0.7 deg
Front toe +0.17 deg
Rear camber -1.9 deg
Rear toe +0.22 deg
All within specs with rear camber on the aggressive end (stock specs: -1.4 to -2.1)

Make sense?
Koni recommends the FSD's for use with the stock springs only. That's the way I'm running mine.
While the initial performance may be ok with h-sports, I am quite curious to see the effect of 25,000+ miles on that set-up.

I am running FSD's now with stock springs on my 03 MCS. The ride is much better with no sacrifice in anything except my wallet and a long weekend. I think they are also slightly quieter although I mixed other mods so it is hard to tell. I was already on non-runflats, but very short ones 16" 40 series. BTW 16" 40 series non runflats ride better than 17" 45 series runflats and are much lighter and cheaper.
