can I get a price on a 4250 with and without springs and spherical top hats? I'm just curious and might be inquiring about them for my friends RTR CR build.

I love ASTs but I couldn't live with just one adjustment...

for the money though they are for sure the best single on the market.

It is probably the same price as the 5200's since I'm told that they are pretty much the same now. Not sure how much those are though.

Josh, your inbox is full. As stated above, the price for a currently 4250 type build would be similar to the 5200s. The true 4250s (internal double adjustable) won't be ready for quite some time unfortunately.

Hi All, four sets of the 4150s will be showing up to our shop tomorrow, with the rest to follow next week. I will test out ASTs recommend spring lengths to ensure that everyones desired ride heights will be in check. I will be in touch soon. You can always reach me here at the shop or via email.

Here as the shock dyno that AST sent over today. We may have them shock dyno'd here as well since we are having some things for another chassis type checked out.

Can any shock guru's comment on this graph? It seems kind of soft for 600 - 700 lb springs.

Just to give you an idea of how soft here's a dyno sheet from PSS's

Revalved PSS's for comparison

The only way to really know is to drive on them, the Bilstein dyno's are by no means something that's proven or even considered good.

Another week or two and I should be able to get them on the track. That's my hope anyway. Still need to actually GET them and get the car setup.
