with completely stock setup in the front
stock torsion
stock sway (15mm)
stock shocks (unknown)
stock rear shocks (unknown)
stock rear sway
140# springs
this could give you a whole lot of oversteer. More than you may want. Unless you like a REALLY loose car, especially on 195s.
I think you need to check into what you really have before you start changing things.
what kind of shocks front and rear, and in what condition
how old and really what size your front torsion bars are
after you determine that, consider this.
a very widely used setup for stockish 914 2.0L was as follows
front- Koni adjustables, 19mm adjustbel sway bar, stock torsion bars
rear- Koni adjustables, 140# springs, no rear sway bar.
with this setup you can adjust the handling to what you want either push or loose
(understeer/oversteer)
just throwing springs at what you currently have may not do you any good at all.
find out what you really have before you start adding parts.
I have been AXing and time trialing very basically set up 914s for years and this is one of the setups that worked well for me and many other 914 owners in Norcal.
my 2 cents
