RE: Solid Motor Mounts and Torque Limiters
Good find!
Summit's part # is PTP-6-505-BL

I JUST purchased these two items...(i would use the two in conjunction with each other...read on)
the Prothane Bullet Mounts and the CHE Kmember brace w/ torque limiters...
I'll be installing both fo them this weekend...
Good to note:
I found the Prothane mounts sold at about 10 place..so i did do some good research...
Summitracing.com had them with the red bushings for $165 and with the black bushings for $103!!
So curious as to why the price was different I called summitracing and Prothane tech departments directly...
Prothane said the black ones have slightly more graphite in the material, which means nothing for performance only ads a little bit of sparkle to the black color, the busing tolerance and flex is identical, prothane said both retail for the same price (about $165) he wasnt sure why summit would be charging diff. prices...
so when i called summit, the tech guy essentially said the same thing, that he has no idea why they're different prices because his spec. sheets listed them as identical products...
so before they changed the price to what it should be I got my Prothanes for $103...what a steal if you ask me!...
Now the main reason for the mounts is because my FRPP shorty headers hit the steering shaft on hard left turns and when hitting the gas in reverse...so the mounts by themselves should fix the engine issue...
and I got the k-member brace and torque limiters to help stiffen everything up again (as well as the engine)...however I wouldnt use the torque limiters without additional support...because the torque limiters attached thru the back of the tranny bellhousing...which means all of that movement the hydro-mounts allow, is being sent directly into the tranny housing and I'm not sure it's really signed to do that much "torque-limiting" That is why i did the mounts and k-member brace w/ limiter together....
after the install this weekend I'll repost to see who everything fits and if the functionality changes and vibration is affected.

The bullet mounts are very nice quality, and like you said they are much cheaper than the Steedas. I'd buy them again in a heartbeat.
As for the LCAs, I would be wary of the CHEs. Yes, they do have the bracket for mounting the parking brake cable. But, on the other hand, they don't have grease fittings for lubricating the bushings. The BMR and Spohn ones do. No grease fittings is a big negative IMHO. The parking brake cable is easily secured with a zip tie.

This is not true. The Torque limiters attach to the block, not the bellhousing. They do go through the bellhousing but they are threaded into the block. The area where they attach to the block is about 1" of threads or so. (It has been awhile since I installed it). If you look in my thread about this you can see in one of the pics the load will go into the block not the bellhousing. The bellhousing is a clearance hole even.

RE: Solid Motor Mounts and Torque Limiters
I have not installed them yet...but if they PASS THROUGH the bellhousing then they absolutley put pressure on it as the engine torques...granted most pressure is likely on the threads that are in the block, but if the bolts touch the bellhousing in any way then there's no choice but to put pressure on the bellhousing...
either way, can't go wrong with the engine mounts as well.

RE: Solid Motor Mounts and Torque Limiters
The hole in the bellhousing is a clearance hole. the bolt does not touch it when installed. The TL does touch the belhousing and it will indeed put a small amount of load on the bellhousing when the bolt deflects, but it will be a very small amount. It could be possible for the bolt to deflect enough to contact the bellhousing as it is only clearences by a few thousanths but by far the majority of the load will have already be transmited to the block.
That said I am not trying to attack you for buying both. I just don’t want to see anyone get scared off from buying the TLs.
When I first started looking into them I was not going to buy them because I thought they attached to the bellhousing. Which IMO would be a disaster waiting to happen, But I talked with Mike@powerhouse and got some pics of them and found out there is alot block it is attaching to.
For other buyers out there I would not be afraid to recommend the TLs without motor mounts. The powerhouse car is running 10s (If I remember right) with the stock mounts and the TLs.

+1 - I Have been running them with stock mounts for a while now, with track launches, and no issues. I put them on a friends Roush when we installed his Whipple and he has had no issues with the stock mounts. Not saying you shouldn't do the mounts, just not a necessity.

Ok now....looks like the consensus is that they are not needed together....
I got the mounts to correct the headers/steering shaft problem, and the K-member brace to help stiffen the front end and got the limiters for ****z and giggles and what the hell-couldnt hurt right?...
Certainly seems that the torque limiters themselves would help alleviate the headers/steering shaft problem...but for $103, cant go wrong with stiffer motormounts also.
