Really happy with both upgrades although I won't realize the performance difference until I get to Roebling on 23 March.

Just bedded the rotors in tonight so not any hard use. They are gorgeous though

I was amazed with the difference engine mounts made. Again, actual performance difference will have to wait for the track, but the difference in feel and sound in the car is exponential. It sounds like a mini cup car...I've ridden in one with Hurley Haywood Of course a cup car is much louder, but the sound and feel is turned WAY up.

 

Nobody will come away from riding in my car and say, "new Porsches are not raw enough," LOL.

 

Very nice - how would you describe the difference with the engine mounts? Very interested.

Best,

Matt

 

Today was my first full day with the mounts. Things I noticed different with the mounts, keeping in mind when I took the stock mounts out, I held it in two hands and could easily move the mount bolt around the very malleable rubber bushing. The mounts are perfectly normal, only 42K miles.

Observations:

The sound in the car is as if there is nothing between the cabin and the engine compartment.

There is a slight vibration increase as seen by how you can't see in the mirror behind you well enough to identify what kind of car is trying to keep up.

When rowing through the gears, at greater than say 4,500RPM the power goes down immediately...you may think it does now, but there is a noticeable difference.

When leaving a four way stop turning left in a four lane intersection I put the power down in second and the back end broke loose because you do not lose ANY power or torque due to engine mount flex.

These are not for the faint at heart. I'm pretty hard core, liking my daily driver with a stiff suspension and loud, but in the first 10 miles I was wondering if I would leave these mounts installed. I have grown more used to them today, enjoy the rawness they deliver and I am pretty sure they will stay...next is to convince my wife that difference she thinks she notices is attributed only to length of time it has been since she was last in the car

Definite increase in smile factor once you get used to hearing every little detail of your engine under load...totally different than standing outside a car listening while someone revs it up.

 

I love mine. The car really comes alive with them at the track.

 

Nicely done Don!

No joke with upgraded solid engine mounts on a daily driver - you guys are hardcore haha!!! I applaud the willingness to go the extra mile for the increased performance for sure, it's great to see these cars being used like they should be!

 

It's actually not as harsh as you'd think.

That said, I went on a drive this morning with my buddy and his 4S with sport suspension. We swapped cars for about 25 miles and it felt like his ride was a cushy Cadillac by comparison, lol.

 

"It's actually not as harsh as you'd think.

It sounds more like you've gotten used to it

It is hard to describe it, but driving to work today I was short shifting because the sound kept making me feel like I needed to upshift...even when in 6th.

 

Trust me... You'll never get completely used to it. But that's a good thing -- The buzz is always there, reminding me to sign up for the next track day.

After a while, you'll find yourself cruising through your neighborhood in 2nd, just so you can pretend you're in the pits at LeMans.

And when I say "cushy", I didn't mean it as a compliment

 

Haha, I'm with you, I didn't think you meant it as a compliment.


I started doing HPDE's last June and now have rented the track for a private track day in March. I am definitely hooked.

 

Thanks for the feedback.

Is changing the Engine mounts easy enough to (DIY) before & after each occasional track-day? Thinking of putting solid mount in before the track day, and swapping int out with the stock mount for DD use.

 

Technically, yeah. Once you know what you're doing, you could get it done in about 15 minutes. But, it really isn't so harsh that you'd want to every time.

 

With my FABSPEED exhaust I have to remove the o2 sensor to get to the mount bolt, which adds another 10 mins. When I first discovered that, I thought it was going to be a PITA, but all you have to do is unplug them and use a normal open ended wrench to take them out. Stock exhaust and maybe other aftermarket you do not have to do that. Yes, agree it is an easy DIY. If you didn't want to use them on a daily basis it would not be a major effort to work them into your track prep process. Right now my prep only consists of track brake pads, wash and wax. Looking to add seat and harness to that before the next track day.

 

Yeah, it's definitely faster and easier than a track brake pad change.

But a word to the wise -- put the car up on jack stands before supporting the engine for the mount change.

I was a knucklehead and just had my car on ramps when I did mine and as soon as I had taken one side's nut off, the decrease in load caused the rear suspension to decompress. This totally screwed up the alignment between the engine sub-frame and the frame. It also sent me into a slight panic because the jack I was using to support the motor wasn't long enough to compensate for the distance!

Knowing what I know now, I'm confident I could swap them out in under 15 minutes, including lifting the car.

 

Interesting. I did have mine on jack stands when I did it, but get a little clunk on turn in (street) from behind. Maybe I need to re-torque with it on the ground.
