I just read the post by fierosound...

http://www.fiero.nl/forum/Forum2/HTML/135687.html


His post came just as I was thinking about posting a question about the steering on my 88 GT.

Although it seems fine at mid to high speed, and there are no outward signs of problems like funny noises or binding, the turning effort at parking lot speed has always seemed to be harder than it should be. That feeling has been reinforced lately after acquiring my 86 GT. Before getting the 86 GT I had nothing to compare it to. The steering in the 86 seems much more comfortable at low speeds. The PO lowered the car and I have been wondering if the lower stance on the 88 changing the geometry resulted in the harder steering.

Or maybe my problem is similar to that in fierosound's post?

Hello, I haven't noticed a difference in lowered 87 SE,

Could be different rack ratios in Fiero's that you have driven in the past

88 rack ratios are all the same. And the racks are not supposed to be interchangeable with other years.

85 - 87 racks have two ratios, GT rack is faster (fewer turns lock to lock) making them harder to steer at very low speeds.

The 85-87 'slower' ratio is 3.5 turns and the 'faster' (GT) ratio is 3.0 turns lock to lock

In the past I have installed racks from the slower 85-87 model Fiero's (SE,Base, etc) into GT's which makes them easier to turn at very low speeds but not quite as quick steering at high speeds

Hope this helps

According to the PO...

"Front drop spindles & springs; approximately 2" rear adjustable coil-overs"

That's all I know.

If the angle geometry of the steering was changed as a result of the lowering, then it will affect how it steers. Do both cars have stock size tires/wheels as well? Wider tires will make steering more difficult, so if your 88 has wider tires on the front, it will feel harder to steer at low speeds.

Don't know anything about the geometry, but both cars are running 205/60R15 in the front.

The steering effort on the 88 should be less than the 86.
The 88 has less scrub radius and slightly slower rack than the 86.

If you change Caster setting then that will change steering effort.
Changing tires and/or wheel(rim) can affect steering effort too.
Both together can make a car hard to steer, especially on cars w/o power steering.
