Caltrac split mono

FireSale · 07-15-2019, 12:58 AM

I had the bolt that runs through the springs and centers the perch shear off yesterday. Tech snagged me in the waterbox because the RR tire was shifting around. Would have slashed the pass tire if he hadn't caught it. Springs had been in the car since 2014. New bolt fixed it.

PS Thanks to the tech at Bremerton for bring sharp. It's an airport strip that has been in operation since the 1950s. Run by a car club and a real step back in time.

Mine settled over time (roughly 12 years) so I did replace the back half with a little more arch than the stock spec for my car.

Never saw a difference on the timeslip; just the outer tire to quarterpanel clearance.

We have seen only very minor ride height changes over 10 plus years
but never any 60 ft. change. My Demon probably has 1000 passes
on it and never changed the springs. John Calvert makes well engineered
products and has exceptional integrity!

If you haven't yet, and you have an automatic, you might want to think about looking at your converter. Had the same problem your describing and after many $$ and a couple of months it turned out to be the converter although it stalled up the same rpm as it did new. Never had any problems with my Caltracts in 10 years of use.
