John,
Interesting that you dont like them, what is it that don't you like them?
What are your thoughts on Torque solutions semi solid engine mounts? I have had them for the past 3 years.

The semi solid engine mounts are fine Jim. I prefer the OEM semisolid RS mounts but that's just me. They're all about the same. I highly recommend the semi solid engine mounts, they're a win win. I'm even tempted to try full solid Cup engine mounts as they do not add much NVH over the semi solids. The transmission mounts are a different story. No matter what they claim, the urethane tranny inserts are horribly loud and if you already have semi solid engine mounts they bring little benefit beyond the placebo effect. I've tried them and saw no discernable benefit over a fresh set of OEM 997 trans mounts which is what Porsche uses on even their most hardcore street legal track cars, the 4.0 RS and 7GT2RS. Unless you're wearing a helmet 100% of the time you're in the car and going for a checkered flag, don't bother...

I have the Function 1st black inset ones and I'm probably struck by the placebo effect ..lol. I have found the NVH was slightly increased but not hugely.

I recently replaced a track suspension with the stock on my car. Other than mild increase in understeer the overall effect on the street has been only positive given the increased ride height and more compliant shocks/springs. I broke it in with a 800 mile trip with all sorts of driving and I was very please with the stock package. It seems like this is your first 911, you'll just have to get used to it. If your stock suspension is in good shape the car will work very very well.

I've had my 03 996TT for about 3 months and driven it less than 1,000 miles. This is my first true sports car so don't have a lot of past experience with them.

I don't know exactly what you mean by weird handling but what i have experienced is while driving in a straight line that the car will all of the sudden twitch (seems mostly to the right). The steering wheel will quickly move to the right and just as quick move right back to where it was. This happens at both moderately low speeds and higher speeds. I live in South Fl. and our roads are constantly under construction and sometimes it seems to catch a groove in the road and just follow it but that is not always the case. BTW, turning is not an issue at all, I have taken 90 degree turns at a decent speed and the thing just seemed to be on rails, incredible feeling.

Unfortunately I was not able to speak to the original owner but i do know it has Bilstein coilovers, Pirelli P-zero tires, and believe its been lowered but not a 100% sure on that. I plan to take it to a local Porsche specialist in my area to have them drive and let me know if this is normal behavior or not.

I don't know if this is what you mean by the weird handling but appreciate if anyone else with more experience could chime in to let us know if this is expected behavior or not.

Forgot to mention that a 4 wheel alignment was done about 18 months ago at the same time coilovers were installed.

As I noted in the other thread, I was having WEIRD driving feedback and an extremely floaty front end as my rear PS2's wore down. New tires (Sumi HTR Z3) feel sooo much smoother and more planted. Havent even been aligned yet and the difference is night and day.

i was just gonna ask about "grooves" in the road as i have probably a hundred thousand miles in these cars and i have never once experienced a twitch such as you've described. the only thing that keeps coming back to me as a potential "cause" is those weird "grooves" that some temporarily worked on roads have.

given you've aligned your car, it should track straight always..

also, when i doubt, listen to pwdrhound lol.. the guy has tried probably very combination of anything even with different engine displacements in these cars ha..

i had always heard good things about the TS inserts, and yet, all i ever did was swap to semi's ( as he again suggests, ) and put in ( again.. ) a new oem t-mount, and i can't for the life of me imagine what i am missing. my car is as "taut" as i will ever need it to be. it really makes one wonder about the FS inserts, and "window weld" mods and things of that nature that some might even refer to as "macgyvered".

but it'd be tough to argue against the idea that it's hard to go wrong with pmna and/or oem parts, when in doubt.

honestly? i think with more seat time you'll begin to figure out what's going on, but also, as as stevenmfr has suggested you should really get someone with a lot of seat time to put 20 miles on the car. this is often invaluable, especially given the difference in the kinds of others that have been your experience. GL w it! and keep us posted also.. the help in here can often be invaluable and sometimes as good as what you pay for lol ( some..... times

oh yeah..put more miles on 'er too!

Think of the 996TT as a point and shoot car. It loves to be trail braked deep into corners. Then rotated quickly at apex and drop the hammer. The AWD system will kick in and rocket the car out of the corner. The 996 Turbo has more grip accelerating out of a corner than any other car I ever driven, and I have driven quite a few on racetracks. That is its strength. Driving it to its strength.

Carlo_Carrera

Exactly.

Adjust your driving style. Not taking a shot at you by any means, you may be a fantastic driver for all I know, but compared to the cars you list as driven/owned, it is simply going to take a different touch.

When I initially bought mine, I felt like the back wanted to slide and the front wanted to understeer.. It was weird, and kinda frightening. Then as I learned how the car communicated with me, I adjusted how I drove it and it is absolutely brilliant.

Go to a PCA Driver Skills event, or something similar, or an Auto-X.. These are slow and open, safer to learn the handling dynamics and limits there compared to being on a road course at higher speeds with other cars and possibly questionable run out area.

This obviously under the assumption that everything checks out mechanically. If you have a mechanical/alignment/tire issue this is all out of the window and you should handle that as priority 1.

Road King

That's it Carlo. Even before I installed the adjustable sway bars I was enjoying the point and shoot style...esp. with my Sambo 1 bar tune as the midrange torque is explosive. My car really squirts out of corners like nothing else I've ever driven, and I've had 500 hp Mustangs, Vipers, and a few STIs.

I have a good buddy who had a 2015 Jag F-Type R with 550hp, and it was very fast and very comfortable. But on the backroads he simply could not corner and rocket out of the apex like my car...the grip I get even from my 'tier 2' Falken FK453s is astounding. I can only imagine what it will be like when I upgrade to GT2 sized rubber.

This is the most fun car I have ever owned, bar none. With my (near) stock suspension it's quite engaging and a bit demanding in the twisties, and I wouldn't have it any other way.

OP, perhaps you can ride along in some other 996 Turbos to experience different cars and driving styles.

powdrhound

I was referring to go urethane replacement transmission mount bushings like torque solution of GMG makes. I would imagine the function first inserts are much better from a NVH standpoint as they retain the factory rubber bushing merely filling the voids. I would say these would compare to the window weld mod. Do you have a 996 mount with the function inserts or the 997 mount with the inserts?

James88

I have the 997 mount with the F1st insert. I Immediately noticed a huge difference with more precise firmer gear changing and better handling.

Thanks...noted.

Appreciated Podrhound...
