Cutting SR Lowering springs

If I cut my SR lowering springs from AM, will it affect the spring handling? I'm trying to lower my car just a bit more.

Taking half a coil or so off is done all the time. It's not recommended as it does change the characteristics of a progressive spring. The load rate is preset when they are made and that will change once material is removed.

I too have the SR springs on my Mach. I removed the isos for the extra .25-.5" to get the drop I wanted. I would try that first before cutting if you haven't removed them already.

I think you'll be happy after removing them. Sometimes that extra .25-.5" is all I takes to get the right stance.

I would recommend wrapping the ends of the springs with masking tape to prevent metal on metal contact and even throw some grease on them to prevent squeaking.

I did this to my 03 when I installed my H&R Super Sports over 4 years ago and it's held up well.

Hey Pj,

Sonic gave you some pretty great advice. Although I would not recommend cutting the spring, removing the isolators will definitely drop the car a little more and not effect anything negatively! I did this on my previous 2004 and loved the outcome.

Hope this helps and let me know if you have any questions.

-Will

Does anyone know how thick the ISOs are in the stock 05 gts under load. I just installed SR as well. Looks good just wanna get it a tad bit lower. I wish I would have read this thread earlier so I would have told the mechanic to just leave to ISOs out and I would have taped them up. Do you think mine are shorter since I have 100,000 miles
