99 V70. Not sure how I tell if internal slave and dual mass? This will not be a daily driver but when I do go out I don't want to do in car left leg squats. I don't have the time or skill to pull the engine/reinstall and mess with the flywheel.I still have my stock 16T, but with plans to go 20T in the near future I opted to go with a SPEC stage 2. I found a lot of people even with just 18Ts that are slipping 850R clutches prematurely so I went with SPEC stage 2 based on lots of comments and research. Stage 3 sounded like it would be a bit grabbier and maybe more leg work than I want on a daily driver, but who knows without feeling one.
The SACHS 707 combined with re-pinning the flywheel seems like the tried and true way to go for those making more power but I didn't have the time or means to ship out my flywheel.
If the stage 2 is stiffer, it's barely stiffer than stock clutch. I only have about 10k miles on it so I can't comment on the longevity, but so far so good. My car is single mass flywheel.
What year is your car >> Do you have internal slave cylinder and dual mass flywheel? Or external slave cylinder and single mass flywheel? The clutches and pressure plates will be different and have different feel between the two set ups even if they are both stage 2. Any given stage clutch and pressure plate for a single mass set up will hold more power than a dual mass according to SPEC's site.
Yeah, there is really only one indy volvo shop here in vegas, but denver is close enough that I would consider the drive up to have it worked on/tuned by JZW tuning. I've seen some of his videos, have you guys had him do any heavy duty mechanical work? I just don't trust myself to pull the head (and there isn't a machine shop in town that my indy would recommend to do the head), and I have no compression in cylinder 4 (95k miles).Yes, '99 will be dual mass and internal slave. Volvo switched the set up in mid 1998.
Will you have a shop do the work, then? Make sure they tighten the pressure plate bolts down all the way!
