Daily driving a solid driveshaft

[Performance nut]

Back from my earlier sports car days, solid driveshafts were something only serious competitors did. Mainly because the car was pretty much unusable due to vibration and noise. Granted, lot of those guys had cams that cause significant lope, solid or extremely stiff mounts, and a whole bunch of other stuff that improved performance but offered nothing as far as user comfort.

Fast forward to today, I am seeing a whole bunch of claims about no NVH on solid driveshafts. Saw quite a few threads on here with mixed results, some saying it is horrible and other saying it is fine. Found one in particular that was interesting that said if you do the driveshaft, upgrade the half shaft (which seems reasonable, no idea why you would do one without the other) or you will get vibration.

So I guess my question is how aggressive can you get with your car before a solid driveshaft is the final straw as far as drivability. I currently have some of the most aggressive springs and shocks you can drive on the street along with some chassis stiffening and anti-hop products. I have aftermarket wheels to help put more rubber at the corners.

I'm seriously considering forced induction and realize stock will likely not survive long forcing an upgrade as I may track the car from time to time. Power level is a key part here. If building everything up to survive the stress of a high power engine makes the car horrible to drive, then I don't want that level of power in this car. If putting a carbon fiber driveshaft and 850+ halfshafts offer minimal NVH and the ability to crank up the power, I'm all in.

I appreciate feedback and user stories on this. Thank you all.

Well when I was NA I went to a one piece aluminum Dynotech. It was one of the best mods I did until going FI. The car was more responsive to pedal and some of the clunkiness was eliminated. Then I added DSS 800 halfshafts. Didn't notice any difference in drivability one way or the other.
Went FI with a RXT - blew out 3rd in two MT82's.
Switched to TR6060 with CF driveshaft and FRPP 1400 halfshafts - one of the sweetest shifting no NVH rides I have ever had.

I daily mine in the warmer weather with no issue at all. I do have a VERY slight vibration but I'm not saying that's the driveshaft at all. I did so much other rear end work at the same time that it could be anything. It's not enough to keep me from driving it in any way. As I said, not saying it's the DS.

So do you think the switch to the CF shaft and FRPP halfshafts is the reason or the swap to the TR6060 made the difference?

Great question - first TR6060 I have ever had so im not familiar with its characteristics. To answer your question, probably all of them contributed but I would guess the CF shaft was the biggest factor, IMO.
