Abro este hilo con idea de que sirva para recoger todo lo que hay que cambiar y por qué.
-Bajar sí pero cuánto?
1,5 cms respecto a la altura de serie?
-Separadores (espaciadores) para el diferencial (Driveshaft Spacers): Para evitar posibles vibraciones en la transmisión al acelerar por desgaste de los inboard driveshaft joints (inner CV buckets) tal y como se recoge en el TSB 02-063:
The axle shaft of the Honda S2000 is design at a stock height. When the vehicle is lowered on springs, or coil over systems the axles are stretched causing some faster wear and tear on the ball joints. Megan Racing have created these spacers to bring back the stock length causing the axle to reached the stock length when the car is lowered.
I installed Megan Racing Driveshaft Spacers to improve the longevity of the inboard driveshaft joints on my lowered car.
Nota: A ver si encuentro algo MUY bien explicado que estuve leyendo en su día sobre qué pasa cuando bajamos el coche y los montamos o no.
Driveshaft Spacer Necessary for Lowered Car?
The short answer is no, you do not have to get spacers. There are other solutions should your car vibrate after lowering.
Let me show you what is happening that causes the vibration.
Here is a pic of the CV bucket and the "spider" (the set of 3 roller bearings that go in the CV bucket).
When the car is new the spider rides on a smooth surface in the CV. But as time goes on it makes a wear spot. This starts to happen by around 20k miles or so (this is very rough estimate based on folks who have complained about the vibration after lowering). The pic below shows what the wear spot looks like:
When you lower the car, it moves the spider to a new spot where it normally rides. Based on the geometry, the new spot is very close to the old spot. The vibration is caused by the spider sliding over the edge of the new spot into the old spot. It trammels back and forth there.
A spacer takes care of the vibration by moving the spider far enough away from the old wear spot so it can't trammel into the old spot. Swapping the cv buckets from right to left and vis versa fixes the vibration by giving the spider a new surface to create a new wear spot.
This is also why ap2 drivers didn't think they needed spacers. It wasn't until the ap1 was a few years old that they would have a wear spot and when owners lowered the cars after they had 20k+ miles on them they got the vibration. At that time the ap2 was brand new...and they didn't have wear spots yet.
Now, older ap2s have wear spots too and can get the vibration for the same reason the older ap1s did.
Is a spacer better than swapping the cv buckets? It depends on your mechanical skill and wallet. Swapping cv buckets is free, but does take time...you have to pull the axles. The 2-piece style spacers can save time and are easy to install, but they are $175-200. The 1-piece style are useless as they take about as much time to install as it does to swap the cv buckets.
-Anti-bumpsteer kits delantero y trasero: Para evitar posible toe-in en compresión en los dos ejes.
Bump steer is one of the fragile points for suspension tuning on S2000. Megan Racing has created these spacers to eliminate some of the front bump steer that is created by lowering your vehicle.
The Honda S2000 was a breakthrough for Honda, being their first full-production FR car with VTEC the S2000 dominated the race track even in it s stock trim with impressive handling and agility. Although the S2K is an amazing car, a competetive driver will always want more.
It s within this understanding that Megan Racing has unveiled our line of reinforced suspension arms that offer the strength and adjustment that any comptition vehicle will ever need. Constructed of high-strength steel alloys that offer durability, strength and yet remain light-weight, these control arms have been track tested for months in road race, autocross and drift events to assure quality and performance.
These Toe-Control arms allow for fine-tuned adjustments to the rear toe in/out setting of the vehicle. Toe is crucial for the straight line stability and behavior of a car and is said to have more of an effect than the front toe.
Note: Will not fit 16" wheels.
-Front Roll Center Adjusters (raises roll center): Para evitar que una de las ruedas traseras se levante y gire loca.
When an S2000's suspension is lowered it's roll center is lowered more than the center of mass which increases the length of the roll moment arm which makes the car roll more than when running at stock height (assuming same spring rates). A roll center adjuster can be installed on the front lower control arm ball joints to correct the lower control arm's angle to raise the roll center to shorten the roll moment and reduce chassis roll. Sometimes suspension modifications can change the roll center. Because the ball pivot is extended to make room for the adjuster, SPC adjustable ball joints raise the roll center.
A is the Center of Mass Over the Axle, B is the Roll Center:

A ver si vamos completando entre todos.
