Steve Spohn, do you intend on coming out with a STB ? will it be a 2 point or 3 point?

I recall Steve saying somewhere about an upcoming STB late this year or early next year, I think in his brake kit teaser post. Might want to do a search. I'll wait for his STB to come out.

Bingo...found it.

Here's some updates on what we have going on. I haven't been on as much lately to keep people informed because I've been busy....we're currently working on buying a larger shop (8,000 sq. ft.), we're hoping to make settlement in October. We outgrew our current location over a year ago, but the real estate market is tough (and expensive).

Once we have that in place we'll have the capability of expanding our product lines and inventory. All R&D going on right now is based around the front of the car. At this point in my business, I truley feel we have the rear suspension designs mastered, and I don't think I can make things any better. We have a few new torque arms coming out for some more transmission swaps, Richmond 6 speed, 4L80E, and LS1 Swap/4L60E/T56. We will also soon be releasing a full length transmission mounted adjustable torque arm.

Within the next week or so we'll be releasing a new front brake kit for those looking for more then what the 1LE has to offer. This kit will have 13" rotors and Wilwood 4 piston calipers, and everything fits under a stock 16" wheel More details on that in the very near future.

That'll be it until I'm moved and settled in to the new shop. What can you expect in early '04? You'll see tubular a-arms, strut tower braces for carb, TBI, and TPI, and tubular k-members. We'll be looking to various things with the k-members, like std. motor mounts, LS1 motor mounts, OEM steering, Pinto Rack, 4thGen power rack. It'll be good stuff. If you're in a hurry, don't bother emailing or calling about this stuff, if you're not in a hurry, you'll see it in '04, and it'll be sweet

Steve
Here's the rest of the post:

So yes, he is coming out with an STB in early 04. I can't wait

does anyone know anything about the Ground Control fron strut tower brace?

They don't have a picture on their website but it looks like they make some harcore race-derived parts so I assume this one might be pretty nice.

It is chromoly steel too, I don't know of any others made of chromoly.

here's the catalog: http://www.ground-control.com/gccamcat.htm

i like my polished hotchkis bar, really made a nice difference too! i believe you will have to shim it to fit a superram but a miniram is no trouble as you can see.

I would at least go with a 3 pt. brace as it is at least triangulated on something. It is a hotly debated topic if a STB does anything for performance or not. The three pt. designs are better, but as far as clearances, I don't know anything about that. It will clutter up the engine bay a little more than a two point, but it adds a little more stability... ah, endless compromises

The main advantage that everyone sees is a reduction of NVH, cowl shake, etc, also some have seen sharper, crisper turn in. Like the car "feels" better, a little tighter up front. I would say if you were to go with a offering right now, spring for the Edelbrock or another 3 pt. design. For me the reduction of NVH alone would be worth the price of admission.

Noise Vibration and Harshness:

"NVH is a car industry term that stands for "noise, vibration & harshness". It is used to describe the group of symptoms that we relate to when we say a vehicle is rough, noisy or harsh.

A good example of a car with poor or lots of NVH is one that has had all the bushes replaced with polyurethane or mechanical rod ends. A perfect example would be a dedicated racecar. Specifically, the items that were designed by the manufacturer to insulate the occupants from the road have had the compliance removed allowing road and tyre movement and noise to pass through to the cabin and occupants.

Spring, damper and sway bar rates also affect NVH. In fact every suspension modification WILL have an effect on NVH. It may surprise you to know that a softer spring can sometimes increase NVH while a firmer spring may improve it.

Another popular source of increased NVH is mismatched springs and dampers. In almost all cases, this will lead to unnecessary increases in NVH. Hence Whiteline’s "Sports Pack" approach that provides matched and balanced solutions.

It is very easy to design the steering & suspension components to link directly with each other making steering and handling response razor sharp, but the NVH levels would be totally unacceptable for road use. The challenge is to design modifications that compromise toward improved handling with out greatly sacrificing NVH levels."

(qouted - not my writing but does a decent job of covering the term )

I HAD A hotchkiss one....Its was a POFS...YES it did its job but IVE SEEN BETTER POWDERCOATING ON A DONUT...

The crap peeled off easily...After looking at others at shows a lot of them were peeling...

Hotchkiss offered no help or explination on the **** poor work...

Ill never buy any of their overpriced CRAP ever again...

IMHO there are companies with much better products that sell for a lot less money out there...

well i agree that they are pricey. however the polish job on the bar is outstanding as well as the smoothness of the welds are very nice. so my opinion of the actual make is good.

as far as performance the bar does what it is intended to do and it works well. i could use it a little lower personally since the miniram leaves so much room but it works. i for one did not want a 3 point bar for numberous reasons so i'm happy with what i have which is why i bought it.

I did not even know they made a polished one... when I got mine it was BLACK or RED....It was Made of STEEL so Yours must be a different design...

All Im saying is***they CANT powdercoat worth a crap...***

then their control arms suck and are waayyy overprices...SFC's suck and are way overpriced...

if you look at the hotchkis website you will see the option for the polished version although they don't show pictures which really sucks. originally only the polished versions where made out of aluminum now supposedly hotchkis claims they all are. either way it's very lightweight and works well. looks very nice too!

i picked mine up through summit racing to save a little bit.

Yeah mine was older..I bought it in 1997...Its was steel because it rusted under the peeling powdercoat...It was still pretty lightweight even for steel..

Hey..Nice crack pipe, btw!

How do you like that intake comapred to the modified cold-air intake?

I've been thinking about doing the crack pipe for a while, but it seems that most cars I see them on are birds b/c of the way the stock intakes are designed. I've never seen one on a camaro b/c most just run tubing from the stock air box (very restrictive) to the grille opening.

I know this is not an "intake" forum, but just curious to know what diameter pipe you use and which air filter fits it and how do you like it? How far down to you run it?

it's 4", running K&N "cone type" general type ($45), ran through the battery tray (relocated to the hatch) aimed as low as possible but not visible without being right under the car.

4" cai, miniram and 4" exhaust makes for a very healthy breathing motor.
