New AST 4150

Saw this on Vorshlag's FB page. I'm close to pulling the trigger and glad I saw this before purchasing the older gen ASTs.

http://www.vorshlag.com/forums/showt...6936#post56936

The parts have been tested, the design is finalized and production begins at AST Holland on several 4150 models in early January, so we should see 4150 models coming to our shores by late January. Vorshlag has the following 4150 models already on order with the factory, and we will be stocking these dampers over 4100s at our facility from now on:
BMW E36
BMW E46
BMW E90/92
Subaru GD
Subaru GR
Mustang S197

Some of these dampers we have on order above have already been pre-sold, so they might not stay in stock here long. We will ramp up our orders with AST-USA as they roll in. Also, the first 4250 models will be coming to us, since we have sets on order. I will post up in this thread with 4250 details as soon as possible, but it will be much of the same as the 4150 but with 4200 style lower piston assemblies. More rugged, more reliable, and still one of the only true internal double adjustable monotubes on the market.

The 4150 pricing is fairly close to the outgoing 4100 model, and in most cases within $100-150 of the old part numbers. That's not much of a cost increase considering the number and breadth of updates these 4150 dampers have. The upgradeability feature (to 4250 doubles) alone is huge, and will be a big selling point for racers that want to ease their way into double adjustables, with less pain up front.

Maybe HPA can comment when they will get them?

We've been running the 4150 pistons (DDP or dual digressive piston) in a set of hybrid 4100 bodies on our Mustang for more than a month and we're very satisfied with them. When the full 4150 sets with all the upgrades (better stiffening support of the shaft, DD-piston, low drag seals) come in we will dyno them and post the plots at Vorshlag. The wider range of adjustment makes those pistons worthwhile.

4150 and 4250 will be available as soon as all the current 4100 and 4200 stock are sold. AST Holland will also need to ramp up their product to meet the demand.

Price is more like $200-300 more tha the old models.


Straight from AST...New 4150 and 4250 can be ordered with a 8-10 week lead time if you are willing to wait.
