I am planning to buy the Spoon calipers, but i find out that it only use the stock size brake pads. Although it has four pistons, those pistons are so small. So I concern it performance. Anyone are using it, please give me some advise please.

 

big difference, really...

 

The main advantages are the light weight (reduce unsprung mass) and improvements in pedal modulation. A 4 piston caliper will also reduce uneven pad wear.

But.....

rotor size and pad size are the same. Generally speaking for braking performance you want to increase the size of both. Larger rotors provide more "swept area" and more braking torque due to their larger radius, and they provide more of a heat sink (absorb more heat energy). Larger pads spread the force of the calipers over a larger area - thereby improving pad wear (for a given vehicle weight) and braking characterictics in general.

 

the weight thing and pedal modulation i can understand, but damn thats a lot of money. If you had the wheels, you could build your own big red setup using some decent sized Brembos for the same price

 

bIg ReD = more weight than stock

 

Correct me if I'm wrong, but since the caliper doesn't actually rotate with the hub/wheel/rotor, the lightness doesn't have as big an impact as lightening rotating mass does (like going with really lightweight rims), but it does have a greater affect that lightening 'sprung' mass (anything suspended by the shocks/spring assembly). Is there an actual mathematical formula to determine the benefit of lightening rotating mass vs unsprung mass vs sprung mass? So basically I'm just wondering how the benefits of lighter calipers compare to lighter rims or lighter racing seats.

 

Your right it does not rotate but does have weight that the springs and shock must move up and down so if you make the calipers lighter its less work for the spring/shock to do. therefor a better/ more efficent suspension...

 

well not exactly the 993 TT calipers (which are the big reds)

I was thinking more along the lines of the 944 Turbo brembos, 4 piston, fit under 16s, ~ same weight as stock....


just what i'd do

 

the strut/shock doesn't move the calipar, it moves the car. the calipars stay in the same place alllll the time (except when you lift da car

 

Brake calipers are part of the unsprung weight. Lighter is better.

 

I think the current Japanese retail pricing on the older (2 piece) Spoon calipers is fair. And the fact that it does use oem size pads is a plus in my opinion.

Oh yeah, the difference between the two is night and day!

 

It had better be worth it for the damn cost..

 

Does spoon provide a rebuild kit for these calipers?

 

Don't worry about the pad size, as our stock Type R pads are already bigger than a lot of aftermarket ones. My friend has a turbocharged 3.2L E36 (400whp beast) and his AP 4-pot ($$) uses pad size no bigger than the OEM type R size.

Bigger rotors would make a huge difference because of the longer torque arm. But in most cases you would need bigger wheels.

 

You guys are right! it is because i am using 15"Spoon rims, it helps acceleration. Also, i agree it will help the shocks and springs too and turning too!

One thing is, i know Spoon calipers will not fit with the Spoon rims. Because Spoon rims is 42 offsets but Spoon calipers need 40 offset clearance, so i need to add spacers. So what i concern is, adding spacer will it affect the ride of the car?

 

I don't see how the offset of the wheel can affect the fitting of the caliper. Isn't it more the inside diameter and inside shape of the wheel that would give you problem?
The offset determines the location of the center of the outer ring of the wheel in respect to the matting surface with the brake hub.
Am I missing something?

 

Adding spacers increases the track width of the car, so it would actually benefit the handling a little bit. Because of this advantage, a lot of rulebooks do not allow the wheels being pushed out pass the fender lip (like a low rider ). It also allows you to fine tune the turning characteristics of the car.

It does have some drawbacks tho:
increased unsprung weight, longer wheel studs may be required, more stress on the suspension components (wheel bearing).

 

How's that Spoon makes calipers that won't work with the wheels they sell??

 

because the make neither their wheels or the calipers...

wheels by Desmond and calipers by Nissin

 

 

Will this Spoon galipers fits stock rim 6x15 offset 50?

What about 7.5x15, offset 42mm Kosei K1

 

Thats **** dont matter who makes there stuff, they do work together or else they wouldnt sell. From Godspeed "Great upgrade and fits behind stock 15 inch wheels! Less than 6 lbs each! Also, allows you to change pads without taking caliper off. Great for track days! Pads not included but e-mail us about Endless pads at special price with purchase of Spoon caliper kit."




Some pics have a greenish color due to low light conditions but they are a bright blue color closest to the bottom picture.

 

Are you guys sure that will be fit with spoon rims, because i have check the spoon caliper, there width from the rotor surface to the end of the caliper is 50mm, and i have checked with mine rims clearance, it only has 40mm. that why i am not sure it fit or not. Do any guys have pictures for spoon caliper in there 15" spoon rims. thank you!

 

15in spoon rims will not fit with the spoon 4pot calipers...you will need 7mm spacers!!!!!!!!

Sorry only found 16" pics
