part one: i've got the stock sway bar in my 914, would changing them to the weltmesiter be considered an upgrade?.. or is it just a subsitute for the 914s that didn't come with them stock?
part two: i've been running into problems overheating. symptoms: after 15-20 minutes on the freeway, the head temp gets up to about midway on the gauge. car continues to run great if i'm keeping up the speed. Once i get off the freeway or slow down, the car has a huge delay on throttle response, i have to rev it up to about 3000 before i can even let up on the clutch, much less, and the rev drops INSTANTLY and threatens to stall. I've been told to check the thermostat that controls the flaps,but i'm a bit confused on the way the flaps and the thermostat works, when it heats up, does the thermostat expand and let-up on the cable?.. or does it contract and pull on the cable?..
(which way opens the flaps?..)

thanks in advance,

Jeff
