I know this mod has been around for a long time to drop the rear height. Wondering if anyone has suffered damage to the body as the isolator distributes the load; in other words can the spring covered with hose dig into the sheet metal over time? Thanks.

I haven't had any problems though I've only done about 15,000 miles since the change. I think I wiped a little synthetic chassis lube on the top of the hose (lots on the inside!) but I'm not sure.

 

Thanks NJ-LE. What's the purpose of the lube? I assume the hose is to eliminate metal on metal contact to prevent scraping and rattles.

Use heater hose that's a tight fit and the inside the hose lube is needed to slide the hose on the spring coil. I think I used a little on top to protect against the hose from abrading and possibly wearing though.

 

what about cutting or shaving portions off the isolator?

I've been trying to keep any stock pieces I remove from the car as is. I suppose you might be able to use a surface grinder to "shave" the stock isolator evenly but I think it would be quicker and easier to slide hose over the last coil of the spring and try them out to find out if you like it. Easy to go back if it doesn't work.

 

The isolator isn't very tall so cutting would most likely cause it to fail; probably will only drop the height 1/2" max. I'm running Spohn's lowering springs but my 9" Moser differential has larger axle tubes than the stock axle causing the rear wheel gap to be taller than the front wheel gap.
