Who's running Fat Cat Motorsports bump stops with NM Springs? Did you trim the bump stops down and if you did how much? Thanks

 

I did a little google search ‘ they look pretty eBay!

Would just go with power flex bumb stops & call it good

 

Well, if you contact Fat Cat Motorsports for info on ther products, they charge a $75.00 consulting fee so I recommend going another route as they charge for product support.

X5 Racing, who sells them said to contact Fat Cat as they didn't have the info on cutting.

 

I'm not running NM springs, but I did cut mine. I'll measure them when I get home and post the results. I ended up trimming them in steps, it seems like 1-1/4" clearance/travel on the rear was about right. Less than that and it got really stiff really quick.

Years ago I tried urethane bump stops with TSW springs and stock shocks and I destroyed the bump stops (they got sheared from bottoming too much). The fat cat stops seem durable in the year that I've run them.

Thanks. What kind of springs are you running?

 

I'm running sport springs in front and 275 lb coil over springs in the back. I have bilsteins with the threaded lower mount and made upper mounts for them. The car seems happy with the higher rear spring rate.
