WTB: 2011-14 GT or BOSS 302 front bumpstops

[drj2k1]

Looking for a pair of factory front bumpstops off a 2011-14 Mustang GT or Boss 302. New or used is fine (can’t buy them from Ford without the full strut assembly). Working with RE Suspension to test and tune some factory height bumpstops for autocross and need stock takeoffs to baseline.

Thanks in advance,
J

If you just need dimensions, I have them still installed on my factory strut assemblies that I removed when I upgraded my struts and springs. But I'm not willing to disassemble them.

But why not use the Ford Performance jounce bumpers?

Thanks for the suggestion, I actually bought a set of the Ford Racing bumpstops and will be running the rear bump stops. Although I could just run the Ford Racing front bumpstops, I've read mixed information about whether they are shorter/softer than the stock bump stops. I'm planning to send a pair of stock bumpstops as well as the Ford Racing pieces to RE suspension to have them rate tested, then have a set of of appropriate bumpstops pair to the factory spring rates.

Sounds like a lot of work, but given the stringent rules of SCCA "Street" classes bumpstop tuning has proven to be very effective with the soft stock spring rates (I've got a few trophies from the National Tour last year in my H-Street Civic Si that I attribute to this competitive "edge").

Would definitely appreciate it if you could send the overall height of the stock bumpstops so I can compare the data with the Ford Racing Pieces.

Best,
J

The FRPP units are softer. I won't be able to get the dimensions until late tonight.
