People are going to want pics.

I planed on posting pictures when my wife arrived home a little early which was a nice suprise. Coctail hour and dinner pervailed. I should have pictures up by tomorrow. Already had a couple calls. Thank you.

Do you know what the spring rates were on this suspension?

[rdkc01]

That is a deep dark proprietary secret kept in the engineering archives at Dinan, so I was told by Dan at Dinan. I know that they are linear rate springs which is a big plus in my book. I have read on another forum that the springs that Dinan specs for the E36 M3 are supposedly 150 front and 400 rear however this is not to be assumed that that is what this application is here.

[spidertri]

Ah, should of figured that was "proprietary" information. I was more curious than anything, linear springs are always good. It's too bad they don't sell the springs anymore because these would probably be a great alternative to the progressive H&Rs.

About 10 years ago I had a ti buddy who did track days. He only had 3 mods...

Quaife Deifferential
M3 front brakes
Dinan Springs

He was very fast and swore by the Dinan springs.

Some internet searching says Dinan used Eibach pro-kit springs in their kits. None of the US BMW tuners makes their own springs, they either use eibach, vogtland, or H&R.

This kit is basically SA Konis, eibach springs, and dinans sway bars. I'm sure if we saw a picture of the sway bars, we could figure out which company makes those as well. It is possible that Dinan made their own sways, but I'm pretty sure this was just a kit of other manufacturers parts that they put together.

Anyone have a picture of the Eibachs? I have to believe if it was that simple Dinan would still offer ti springs on their site... everything else is still offered.

I'm fairly certain Dinan made their own sways. No one else makes a 22mm rear sway or uses stock type rubber bushings.

The Koni's are valved to Dinan specs... or so they claim. Would need to throw one of each in the shock dyno to be sure.

[mohaughn]

The current groundcontrol Koni SA kits use eibach DRS springs. I think Dinan just stops carrying/selling stuff when the market for it drops off. They are selling enough tuning products for the x35 cars to not have to worry about selling springs for a 17 year old car.

Given the cost/premium nature of Dinan parts, I wouldn't be surprised if they were using a one-off spring that wasn't available in other kits. The value really comes in the valving and the fact that an actual engineer sat down and put the kit together, and I would assume that Dinan did more testing than a company like DDM did before they started selling these kits.

If you want something new and comparable, I'd give the ground control or tckline SA's a try. Although, I'm starting to think that the TcKline spring rates are not necessarily the "best," as TcKline recommends the same spring rates for just about every car I've come across. I actually think the AST products look far superior than the Konis when you start looking at how they are assembled and the known weak points on the struts. Koni's haven't changed in years, AST is still actively developing and improving their products.

I agree that there are many better options on the market these days (especially for track use) but for a complete kit with sways, camber plates, and weld in rear sway reinforcements 1200 is not bad. I have a SA GC set up on my E46 and I really like it. I have heard good things about AST and I think they just bought moton. Buying a suspension these days is a bit like buying a computer... soon there will be something better out.

[spidertri]

AST just announced the 4150/4250 which are supposed to incorporate some tech the acquired from moton and improvements to the weak points of the 4100/4200s. I'd love to try a set but I'm happy with my TCK SAs so far. I've been running 400f/500r and it seems pretty good.
