Race rmm bushing failure

[darkstar november]

Hit the track last night for the first time on the nexens the dealer put on my car, had 1 decent launch of a 2.21 60ft and it hopped pretty bad, did this to my rmm


anyone else had an issue with the bushing ripping out? it was torqued properly and installed properly

Call them first, they will for sure take care of you. But the fact that it broke and your not pushing crazy power or on slicks......... hmmmm........

[darkstar november]

im sure they will help me out, i posted bc i didnt know if this was a crazy thing to happen or not.

i have a test pipe and was on meh street tires. didnt think this should break like that

If that happened to your rmm I hope you checked your transmission mount for damage. The oem is pretty weak.

Put the om rmm back in. Beat on the car and all seems normal.

Wow that's crazy. My problem wasn't quite as big as this but I did have some large cracks in the urethane near the center of my mount after only 6 months of daily driving. I'm sure if I was racing it would have been much much worse.

I immediately sent the issue to Corksport and they sent me replacement urethane within a week. I will be checking my mount every month to see how the new inserts hold up. From my knowledge there has been no changes made to the urethane so I'm a little concerned it will happen again. Time will tell and I will post up here if the issue still continues.

What the heck is this? I'm getting rid of this piece asap. JK, mine has been going strong for a good while.

Calling a company AND posting this information is not bad at all to do. The community has a right to know about all things good and bad and shouldnt have things covered up.

got the bushings in today, put them in this morning. the harder ones def have a bit more nvh, but less play in them.

im happy with the customer service and the parts.

stuff breaks from time to time, good companies know this and take care of it when it happens.

I remember seeing this on MSF but at that time the OP fitted the mount upside-down. I guess it's not the case here, but that's the only occasion I've seen something similar.
Also make sure you torque that vertical bolt properly.

I have two sets of spare bushings just in case because I'm aware that big torque and still soft-ish bushings may not play well together for a long time.

I did a few launches as well and a lot of pulls and hard driving, engine braking from high RPM, I've also been through breaking in a Stage2+ Spec clutch kit, and the original set seems to have already soften up a bit after more than one year of use and about 11k miles on it, so I guess it's time for another set.

Next time I'll order from @CorkSport I'll make sure to add two more sets of bushings in my cart, and one will be the 80DURO set just to see how it works for me, because if it will soften up a bit as well it may be just perfect.

This mount is still the best for my linking I came across so far, and over more than 4 years of tuning this car I've had a few mounts to make an opinion.

shit breaks sometimes. it happens. i was on a grand am team for a season and we broke some weird stuff that shouldnt break lol

I would like to hear that list of weird crap. I am toying around the idea of running a pu in SCCA T3 and any heads up on weird broken parts would be great.

The 80 duro is actually 85 duro, and it's stiff as shit. Mine hasn't mellowed out in 3000 miles yet, either. It's definitely a tradeoff, better turn-in and a more solid front end comes with noticeable NVH, especially in cold temperatures.
