Chris, if you decide to get rid of your HKS exhaust I want to be first in line. It really is too loud, you should sell it, I'm sure you won't be able to get used to it

 

cdelena,

I'm in line behind Clovis for your HKS, should you decide to unload it..........

It was a fun meet.
With the top up the noise is awful.
Top down it's great.
Fortunately we get more top down days than top up days.
The plus to the Spoon is the silencer.
I don't like it at full throttle but just cruising down the road you don't hear it.
But as Insomniak said I only used it when the wife was in the car which is rare.
If I were to go on a long top up trip I would deffinately put the silencer in.
I think Chris's mods to the suspension is a great idea. If I were to track the car I would do the alignment for sure but I would be afraid of to much tire wear in my daily commute. I am looking forward to getting the 'X' brace.

but ever since the car just hasn't felt right. I could be imagining things, or maybe something has come loose, or maybe it's the brand new non-OEM S02's I have front and rear, but the car seems twitchy. It feels like it darts to the side every once in a while, a little more steering correction is required in general, and the read tends to grab and let go a little more abruptly. I really need to take it in and have somebody who knows what they're doing to really take a look at the suspension. Going around the skid pad, I had a much larger sense that the rear was wanting to come around.


I write:

There are a variety of things which can make tight high performance cars twitchy. One which got me once was that after an off road excursion (like yours but not on a track) that the chassis was tweeked such that it would not take an alignment where all wheels were dead on spec. We finally found it when I had the crossbar stiffener untorqued the chassis aligned, torqued back up and rechecked the alignment. (it worked--whew)

One way to check this is to place the car on a set of scales (1 per wheel). If the weight on the left front is not within 15 lbs of the weight on right front (and similarly for the rear) then something may be tweeked. (caveat--make sure that there is a driver or a set of weights approximatng the driver when doning this.)

With different weights on each tire, each tire will generate different levels of grip and cause unpredictability (understeer left, neutral right--oversteer right under power, understeer left braking,.....)

Getting an equal amount of weight right and left on both thr front and back is the first step in restoring ability of alignment to keep the tires where they are supposed to be.

Thanks for your post, Elistan! My experiences with STBs confirms yours.

I have HKS and yesterday felt it was too loud after header installation. Today, I felt much better about it. I do think it is lighter than stock; if not, the weight distribution favors less tail heavy.

I was considering switching to Mugen exhaust, but also will live with this a bit before deciding. Exhaust was very buzzy or booming at times yest, not bad today.
