You may have gone to they website that isn't for USA. They are based out of europe. They aren't a company that has a lot of money to spend on marketing gimmicks. They rely on proven products for there reputation, not a cool website or advertisement.

Also for their 5000 Series products they only have products listed for •BMW 3 Series (E36, E46) Some forum members who could be considering their products might be concerned about this.

www.vorshlag.com In terms of people questioning whether or not AST is legit...they own Moton, and having owned shocks from both marques, compete with Moton quite well, and cost appreciably less.

I went for the 550/650 f/r spring rates and they should be here Wednesday!!! I can't wait! Hopefully I can get them on the car not long after but it's cold here in Boston so track season is pretty much over but I'll definitely let you guys know my impressions.
FWIW, my last car had GC coilovers and they were okay, great compared to stock, better than my car with Bilsteins and Eibachs, but not extraordinary. Adjustments to the Konis didn't make a noticable change in ride, I was bottoming out on some turns on skinny street tires, and even blew a front shock within the first year which GC didn't warranty (they told me to call Koni). For those questioning AST, well, on paper in this price range I think it's a bargain over the Koni/Bilstein based coilover packages. The ASTs will probably require rebuilding more often than the Koni's and Bilsteins too so that's also something to keep in mind. |

Harold was in contact and found out about the suspension
"I was told today the the front is an E36, but it has a short body for the extra compression travel on a lowered car. The rear is not an E46, but rather an E30." Harold Harold also said that they must be used with camber plates. What will be included will be Vorshlag camber plates, for an additional 439

The AST 4100s are in! I bought my package from Vorshlag so it came complete with their camber plates, 550/650 lbs/in springs, and their spherical rsms. Everything went in without a hitch and the shop aligned the car but only lowered the car 10-20mm since one of their scales was busted and cross weighting wasn't feasible. More camber, less toe, full soft, and no change to the rake of the car.
The new set-up is excellent! It has only been two days and the limits are more than I can explore on the street so I'll have to wait until winter passes and track season comes back to New England. That said, this set-up is way more comfortable than the GC set-up on my old M5 set to full soft despite having higher spring rates. There's a lot more feel transmitted through the seat thanks to the stiffer everything but small irregularites in the road and tiny bumps are comfortable. Way less bouncy than stock and in transition the new suspension takes a set much faster, love the decrease in body roll. Though stiffer, there's a lot more grip to the rear over uneven surfaces and less of a tendancy to just skip across the asphalt that the stock suspension had. The front changes direction way better now, most likely due to the additional camber than anything else but it feels great all the same. The downsides - while irregularites are pretty supple, even small pot holes are teeth rattling and I'm on stock 18s. I'm getting some rattles and squeaking from the rear suspension like something is loose which the shop attributes to the spherical rsms and I need to find a solution to being able to access the rear top adjusters without removing the whole trunk lining. Overrall, I'm very happy with the suspension and glad I went with this over GC, though I do have to dodge potholes and manhole covers a lot more aggressively. Oh, stock car weighed 3224 with 1/2 tank of gas and RPI exhaust before one of the scales freaked out. |

Maybe some context will help, I live in Boston and we have pretty much the worst roads anywhere in the US.... In fact, I've had two friends who have driven into potholes and not come out which required a call to the fire department to have the front wheels of their cars lifted out and I even blew out a front shock mount on my old e24. I've lived in LA, NYC, Chicago, Atlanta, Maimi, London, and even small islands in the Caribbean and there is nothing quite like the roads here in crappy parts of New England
In that light, I have definitely see some scary potholes on a regular basis so it's all relative. A small pothole here is bigger than anything I've seen in the state of California.... Ever ... And the new suspenion does make those a much harsher experience than stock. Certainly stock is a more comfortable ride, I was just comparing this to my older GC suspension on my M5 which I thought was even harsher over the small irregularities and bumps in the road than the AST set up.... And equally scary over the big potholes.... |

I am currently thinking about ASTs for my Z4 M Coupe for autocross and street and will probably decide December or January (I am still wheel hunting). $25 off of $2538 doesn't feel like much though. I don't know what the monetary cost is of shipping. Will let this thread know if I decide to go with this buy. Thanks for initiating.

I am sooo surprised that more people on this forum aren't into the AST. It is by far the best suspension for the money. Most desired for a track car.

I am checking price availability on 4150 with Swift spring 400/500. People seem to like this combination for street and track. I currently have TCK DA/SA 500/600. It performed well on track. On street, it is a bit stiff. The car lose traction going over bumps at high speed.
