Post lowering springs only affect handling?

would just 250 lb weltmeister lowering springs and adjusting the rear bolt to lower my car affect handling? or would stiffening the front create more understeer? let me know

It would cause more understeer...
stiffening anything in the front = more understeer
stiffening anything in the rear = less understeer/more oversteer

This includes sway bar changes as well as spring rate...

Most recommend a stiffer torsion bar as well...I think 27 or 28mm...not sure though.

Generally, the stiffer you go up front, the more understeer you'll get (stiffer in the rear, more oversteer) - HOWEVER, the springs will also have more control over weight transfer, which can also play a big roll in over/understeer - this only works to a point, and 250# seems to be that point - as indicated by user testimonials... the 250# simply makes the car handle better overall with no noticable increase in understeer.

There's a bunch of info in the archives regarding this very question.

Good Luck!

Beware of lowering your car!
Lowering your front will cause more stress on your a-arms, which are already a stressed point on your suspension.
A failure of the a-arm or ball joint can lead to catastrophic results!

I agree to a point. When I had my 250# Welts on before I did my torsion bars the car handled much better..that is until I got it on the track. It had a lot more understeer when it was pushed hard. The 28mm torsion bars and 951S sway bars fixed that though.

Cool

Confused now?

Here's the deal. The 944 is a nicely "balanced" car from the factory, grossly under-sprung but "balanced". The trick is to increase spring rates while maintaining the balance. To do this most effectively you need to do both the front springs and the rear torsion bars. The catch is that the torsion bars are a real pain to do, unlike the 911 where the factory saw fit to leave an access hole (sadistic enginers). As Skip said you can get away with the 250's. They do make the car handle better. In that you own an early 44 your car has steel a-arms which are not as much of a concern when lowering the car. Supension systems are just that integrated systems change one thing and it effects everything else. Belive me I just spent a long time getting mine back in ballance, of course now it handles and sticks so well it's scary.

if you stiffen up the front, wont it help reduce nose dive when braking?

Yes - and good dampers will slow the immediacy of nose-dive (modifies the reaction time of spring compression, making it manageable)
