    Driving first is a good idea before you go crazy with add ons.
    Find out how you want to enjoy it.
    Good shocks are always a good investment.
    For 2WD off road. My picks.
    torque or gearing, tyre selection, weight distribution, suitable shock valving, suspension travel, LSD or locker, belly plates, tow points.

    I'ts mostly for clearances in case we are off road, no real intentions of rock climbing or adding bush pin stripes..... We love our camping and like to get on the beaten track but that's as far as it would go in terms of off road. Had plenty of that with the Wrangler. I also want the lift because it looks mean as Sh#t!! I've never owned a sedan and like to sit high, not in a go-kart. Lots of good info here today. Cheers.

    How about just going for taller tyres?

    Yikes guys, you sure have made this sound difficult.

    IF you are raising only an inch or 2 and not extending your shocks. You probably wont have any problems with stock CVs.
    Take your originals apart, clean and replace any worn ones and make sure they are properly clocked. You can race prep them while you are there too.
    Info on this can be found on the blindchickenracing website linked earlier.

    If all your CVs need replacing anyway, purchase 944 CVs from the likes of pelicanparts, they are straight bolt on. If you buy them local check the part numbers before install, otherwise they will sell you kombi CVs at porsche prices.

    Most of the CV boots now days are rubbish and won't handle the extra angle as mentioned. Universal boots such as those from PTW work well, but you will need to keep and modify the retainers off your old boots to make them fit.
    I can help you with this and source you the boots if you wish.

    You definatly DO NOT need 930CVs

    That's interesting, I will need to double check, but am certain my 411 has the same CV's as the beetle/type 3. It possibly changed in the later years (early years never sold in the USA). Also can't see why a 411/412 would need a greater angle CV? The wheel is slightly behind the GB out put, but not a big angle back. Stock suspension travel and engine HP not that different to a type 3.

    Curiosity question, I have seen a lot people braking CV's on forum's etc. I'm curious to know how they "break"? I have replaced plenty of CV's in the past, and have always had plenty of warning before getting around to replacing them. How far do they need to wear before something breaks? Or is it just excessive load/wheel travel that causes breaking?
    Maybe I have just been lucky?

    In searching after Nils alerted to fact Type4 CV still avail able one site discussed the earlier models as per type 1 . later or 944 fit bus.

    Seems a lot of CV other than gkn/lobro have either poor build or failures.
    Mine had some from eBay seller Suzuki ?? something.
    Crap CV and worse/ total fail in backup. Too tight and clacked from new.
    Marks problem was a torsion bar issue but I think it was the different brand CV that had less tolerance and failed ??

    Like most things. Go for best available that has shown good results.

    Failing to clocking the CVs can add terrible vibrations and stress's even if you spent the dollars on good CVs

    411 use Beetle CVs.
    412 use a different CV. Maybe because of power increase with the 1800?
