Just a reminder, the bump stops for SCCA must be the approved Fatcat kit. No other kits are approved. I would expect to see this being teched at Majors in January so make sure you have the proper bump stops installed.

Is there a way to tell by looking at them?

I will be looking at SM, assuming my SRF3 sells. How do you tell the difference between a Fatcat kit and other bump stops?

See attachment - the other kits do not have the washer anodized in red so that's an easy visual check.

On the topic of guaranteeing authenticity, I've spoken with Speedthane, the bump stop supplier, and can have a new mold made (my cost $5500) with additional markings on the upper and lower bushings plus the bump stop. This would be similar to what's on the black urethane isolator you have pictured above. The mold would take 2 months to make and new parts could be available by January but I can't guarantee before Majors.

 

If a visual inspection per the document above is sufficient, let me know. I wouldn't mind saving the cost and hassle on a new mold but I want to make sure racers have confidence and the SCCA tech shed has an easier job with enforcement. The difference in appearance between the precision cut done by Speedthane and the illegal hack job done by dave wheeler @ advanced auto is very clear.

 

I spoke with Xavier C @ NASA on Friday and he is fine with phasing in new MCU parts (bushings + bump stop) over the season. 

 

Todd, I left you a voicemail on Friday. Feel free to contact me at suspensiontruth at gmail dot com and I will keep a window open on this forum as well. I also want to have a conversation with you / SMAC about shock rules / testing as I've created several videos on the subject (topic for another thread).

I think that perhaps before you go throwing stones, you take a moment and remember why others had to make kits - because you could not supply them.

 

We have a handle on the shock rules, thanks. I've seen your videos and what you are doing is ILLEGAL!
