This is with the car on the ground at roughly 13" from axle center to bottom of fender.

 

Just got an email back from AST as to the rear casing length. They say:

 

Any chance they'll give you an exact measurement?

 

I'll see what I can do.

 

For some odd reason 13" comes to mind for the Motons. Double check like you're doing though

 

When I had my AST 4100s I don't think the rears were quite that tall. They were about a 1/4" taller than the KW Clubsport and V3. And I'm talking center of bolt hole at the bottom to top of the shock body.

 

Yea, your AST's from what you said were 11.5" which was too long to run an upper spring perch and spherical top hat.

 

Not ASTs but my custom lenth JRZ triples are 10.5" from the bolt hole center to the top of the shock body. This allows me to run at 12.25" from hub center to fender or 3.25" from ground to jack points. At this height I have plenty of shock travel for even the bigger bumps on the street.

Say hello to my little friend!






Relevience- I also think the AST bodies should be shorter off the shelf for people that want to run really low and still have bump travel for driving on the street. Just my input.

 

Yes, my AST 4100 aluminum bodies are 11.5" long in the rear. The car is very low, but I don't think I hit bump stops except at Grattan (get tires off the ground in a couple of spots..). Granted, if they could be made an extra 0.5-1" shorter that would for sure clear up the issue no matter how low somebody wanted to run their car.

 

If they make them too short won't the droop be messed up for the people that aren't super low?
