GB: Chassis Stiffening, Gauging interest in Spoon Sports Rigid Collar kit
 

7ers,

With most of our cars passing their 20 year anniversary but still seeing track time, it makes infinite sense to stiffen the chassis as much as possible. There are many solutions that either cost an arm and a leg or involve 1000s of man hours. Solution:

1. Spoon Sports Rigid Collar:

2. Various Braces that add weight with unproven engineering.

3. Welding: Time & $$$$

4. Full Roll Cage: Impractical for road car! This kit would add further stiffening to a caged car!

So after contacting Spoon they have an FC kit but have not developed an FD kit. This thread is to gauge interest in a simple and inexpensive kit that could make a big difference for the amount spent ~ Aproximately $250

I will forward this thread to Spoon so they will develope an FD kit, so don't sign up unless you are willing to purchase within 6 months.

Spoon Sports does make this kit, but is solely distributed under RE Amemiya. It says that Spoon Sports manufactures it directly on RE Amemiya's site. When I purchased these from RHD Japan, it has Spoon Sports printed on the box with an RE Amemiya sticker.

Ok I am confused...I was specifically told there is no kit, have you installed this kit, what were your impressions?

If this is in fact true, I will confirm it and maybe we can get a group buy at RE Amemiya, my desire was not to profit just get the kit made!

Wow, wish I knew about this when I asked about

I may be interested if these do in fact help alignment.

BTW, yen is at an all

Yen is at all time low that is

Cool ideaa.

$420 is an awful lot for some collars. If it was $250 or less for the whole car's worth, they'd probably sell better. I realize there was some development time, but seems like something you could draw in CAD and have 3D printed or CNC'd for $150.

I am still gonna try a GB with Spoon...will contact them Monday and try to negotiate 250...

25k yen is ~218 USD. That's not too much over your GB price with shipping.

Now, if anyone has manufacturing contacts that can reverse engineer these things, there might be a little bit of money to be made, while providing a good price to fellow members

Unfortunatly, i do not have any said contacts

Front and rear kits are almost $500 shipped, so $250-300 would be wholesale

I thought I read that the fd came with some type of ridged collar. I guess that info was wrong. I would be in at the $250 price for the whole car.

Well I'm down for a GB if we get them for a better price

Talked to Spoon Direct...

Here is the best they will do...£260+6 shipping ($422.31) shipped to me...This is with me not making a dime or getting a discount...and only if I can get an order of 10 or more...If it's a lot more than 10 orders, say 25, I might be able to get them for £250+shipping ($400)+shipping from Texas say $10...

IMHO I honestly believe every FD needs this mod...

^ Can you explain what type of benefits people would get from installing this? I don't really understand what this is meant to improve.

Just to be clear...

The most anyone would pay for the entire kit F&R is about $435 shipped, also if we do paypal I will have you paypal Spoon direct and keep me financially out of the loop...

My involvement is simply to make sure the parts are available, I am not receiving any personal discount...

Think of it this way...if the car is tighter with less suspension movement and better NVH what is that worth to you...I say >$500 is money well spent!

After watching the video it makes perfect sense...you improve the geometry of the suspension pickups by eliminating subframe alignment & movement...

The aluminum acts as a weld or crush point to eliminate this movement...

Ok after doing some research...this is a rockin' Deal...

1. The spacers are not aluminum...it's a very expensive blend that is proprietary...

2. Try to get these for better price...a single set is at least $500 shipped

3. Some places that offer them, do not have any stock on the shelf.

4. This is a great DIY which I will publish and a great Winter project that will add long term value and improve handling!

5. This package is proven "."

Finally, nothing is cheap in Great Britain, look at how expensive F1 is, but the engineering is legit!
