Hello all

I posted about an issue for my friends racecar we are sorting out awhile back and you guys were great help.

We started putting his car back together this weekend and looked at the stock motor mounts. Then figured may as well do solid ones. Watkins racing has a beautiful set that lowers the motor an inch.

My question is what else needs adjust with these. I imagine it would change the pinion angle. He does have an adjustable UCA. Perhaps this will also require a different tranny mount?

All thoughts appreciated.

Thanks

Jake

My motor is also lowered, though it's a 3V. Just had some clearance issues with the steering column hitting the headers but everything else was fine.

Is this a street car or a race car? I'm wondering if solid mounts are a good choice for your application.
Back in the day we quit using solid side mounts in stock cars because it would sometimes pull a hunk right out of the block.
The motor moves and the frame moves and something has to give. We finally went to front and rear engine plates and that did the trick. Solid is really only good for an all out race car. Drag cars use them, not sure if they are using them on road courses.....but I wouldn't put them on mine. Just my 2 cents.

These are the EXACT things I'm wondering. It's a full on race car absolutely no street driving. Full cage etc. I would love to hear others thoughts on if it is even a good thing for road racing.

Thanks for your thoughts.

I see it says drag racing in the ad, so who knows. I'd call them. Maybe they figure there is enough flex in that long mount that its not a problem. I have the stock aluminum mounts and poly urethane isolaters. 4 years of street driving, drag racing and now road course work w/700 rwhp. seems to be working just fine so far.

Why did you decide to go with solid? We were just thinking more power transferred to the drivetrain. Who cares about vibration in a track car. My concern was breakage or too much vibration causing issues.

You mean on the oval track cars? Stock rubber mounts would often rip under the constant on and off and on and off the power lap after lap. It was all the rage for a while until people started breaking things.
Engine plates worked great and left plenty of room for headers etc. Hard to break a whole block in half but it's happened.
When you wreck and the motor is 100% part of the frame bad things can happen.



Yes, I would be worried about breaking stuff, but again, I would call Watson and ask them. Maybe I worry for nothing.

Fabman thanks for the input. I'm leaning more towards keeping stock.
