Just looking for advice on this.

My car shutters when engaging the clutch in 1st. When on/off the throttle, the car bucks like freakin crazy.

There's definitely a LOT of slack in my driveline somewhere.

Seeing as how the shifter bushing are non existant, I can only imagine the engine and tranny mounts are the same way.

Would I be better off just buying the $60 Engine torque brace, and saving some money, or will the only real way to fix this be buy dropping about $150 on the engine and tranny mounts?

(also, are there any Mazdaspeed mounts I can get, which would be more solid?)

I would recommend replacing the engine and tranny mounts first.

The engine torque brace (IMO) will help eliminate further driveline slop AFTER you replace the engine/tranny mounts. If you decide to go w/ the engine torque brace first, you have only applied a temporary band-aid to mask the real problem.

Mazdaformance has the "Mazdaspeed Motorsports" mounts that you need. (Motor, Tranny, and Differential)

Mazdatrix and some other reputable RX-7 shops may be able to get them for you as well. These mounts are made of a rubber that is significantly stiffer that the "normal" OEM offering.

Putting the engine brace in without first replacing the mounts is like a band aid on a festering knife wound...

Get the mounts.. you'll thank yourself.. get them from mazdatrix, and while you are at it, get a shifter bushing kit.. you won't believe the difference, takes the slop right out of the shifter handle.

I have pulled engines out and had the mounts fall off on the floor cause the rubber had split in two.... this is a BAD thing....

The biggest thing the engine brace helped me with was shifting into third on the strip... it made it MUCH more precise and i haven't done the accidental shift into fifth since i put the brace on

thanks guys. That's what I'm thinking.

So is it a real bitch to replace these?

btw, how many of each do I need? From what I'd imagine, I'd need two engine and one transmission. I've looked in the manual, and it shows a picture of the engine mounts, but says nothing about them, and doesn't even show a tranny mount. Could someone let me know? I plan on buying these soon. Thanks.

two motor mounts for sure, and one tranny mount, i gotta buy a set soon too

You need two engine mounts and two tranny mounts.

I'd also replace the trany crossmember along with the tranny mounts. My crosmember's middle rubber peice was 99% gone.

I agree w/ 1987RX7guy's comment about replacing the tranny crossmember. Just be sure to order the right one.

cool, thanks!

I can't stand the shakiness (for lack of a better word) of my drivetrain! Driving around the city is so damn frustrating. Now I just need warmer weather to show up so I can get this done
