"Passed" means it was somewhere within the wildly variable range of allowable specs. Nowhere close to an optimum setup for handling. And if you changed springs and didn't get another alignment, then that's a fail as well.

You can be within factory specs and have a 'good' alignment. You can also be within factory specs and have an objectively bad alignment for performance driving.

It'll go down the road fine enough, but you're losing a lot of feel and performance.

So the fact that you're asking these questions sort of proves out the assumption made by others (and myself, tbh) that your experience/ability to tell what's good or bad is lacking. Not a slam - just stating what seems to be obvious.


And yes, the factory alignment specs are decidedly less than optimum for handling. The tradeoff is better tire wear, less tendency to tramline, more braking stability, etc. But if you want a car that responds well to steering input, those other qualities will suffer.

You have some homework to do. If you don't know what an alignment is, that's the first place to start. Look up camber, toe, caster, and how each one has an effect on the way a car handles. Do that, tell us what you learned, then we can move on to the next step. Don't even say a single word about your "next build".

meh homework is lame, either OP will spend two hours reading wikipedia articles about vehicle dynamics or he won't. Telling him to do so won't change that.

Uh-oh. I am going to open a subject that has already been done to death but you know, because internet.

I made fun of the rear strut bar BUT the front strut bar is a different matter. Myself and many others have commented on a marked difference in feel after having a front strut bar fitted.

This post sums it up well:

I recently received my GS bar, and was keen to see the difference this modification would bring to the feel of the car. With the help of my brother we came up with a homegrown blind test. (Both my brother and I have science backgrounds and could be fairly accused of suffering from mild OCD ).

The test was this, done five times.

A. My brother would toss a coin, heads the bar is installed, tails not.
B. In either case, step A would take fifteen minutes.
C. I am not in the garage and cannot hear what he is doing
D. My brother when finished step A and B would then pack up the tools, toot the horn and leave the garage.
E. I would take the car for a fifteen minute drive. Same circuit each time, I would note down whether I thought the bar was in or out.
F. When I returned, I would signal with the horn, leave the garage without crossing paths with my brother
G. At the end of five tests, we compared the results.

My brother had out, in, in, out, in.

I had out, in, in, out, in.

I don't want to scare anyone with how OCD I am, but the chances of me guessing correctly this sequence is one in thirty two, or a little over three percent.

Apart from having an enjoyable afternoon spent with my brother having some fun with cars, which we both have keen interests in, I am happily convinced this modification does make a difference for me.

For me it was clear very early in each drive whether the bar was in or not. The noise from bumps was subdued, the steering felt tighter and sharper and the car felt stiffer. I know these are all seat of the pants observations and hard to measure, all I can say is that for me I noticed differences that I liked and when I noticed these differences, it lined up with the bar being in.

So for what it's worth, I am satisfied that the bar makes a difference for me, which I very much like.

Ralph.

If what I share is not of use to you or you feel what I am saying is wrong, you are welcome to correct it, but, "don't even say a single word about your "next build", is a bit harsh. I'll make sure to seek your permission the next time I post.
Typically when someone reviews something they're somewhat knowledgeable about the item or subject...

I'm planning on getting in some track time this summer. Agree, stiffer is not always better. Learned that the hard way, but at least I learned. My driving skill level, IMO is a 3/10, if 10 is pro.
You're welcome. We all throw money at the car buying parts. Although it is not always ideal, if it makes us happy...
Suggestion to get some decent(not entry level) brake pads and brake fluid, and add some camber(2++) up front with some camber bolts and you should have a good base for the track.
