That is really interesting. The AE springs are not really intended to be a progressive spring but I guess the way they wind it it comes out that way.

The AE springs are extremely progressive for the given weight and arm length on 1/12th cars. This is why the longer upper arms are getting popular. You get increased leverage to compress the spring and it makes the front roll easier

To add to that statement, The new front springs allow for a more smooth roll than a slightly longer arm with the added benefit of the quick transitioning speeds of a short arm. When you lube the kingpins the front actually feels like it has shocks on there. Its a real nice feel. It feels softer than you will be used to but the car doesnt touch down. I was amazed at how even the car rolled. All 4 corners of the car rolled even and absorbed the weight which allowed the car to stay more flat and stop the chassis from touching on the track surface.

Thats should be "The elusive Jason Breiner"

....and the "Almighty DB12R"

Makes me wonder how much more progressive the progressive springs we used to run instead of the AE springs were.

will the pod droop adjuster be something that can be easily added on to existing DB12R's? When will it be available?

Considering the existing AE springs collapse almost immediately from the diameter vs. the pitch being so coarse, I would imagine a more progressive spring would have a much shorter life. With the 1/10th pan car they have also gone to more linear front springs for the same reason. People have been running wolf front springs in 1/10th pan cars for years due to the larger diameter and more linear spring tension.

I will be back on that very soon. It will be a direct bolt on to the existing car.

Been so long I can't remember. They were basically what we use today for the side springs on link cars.

We currently do not have any dealers in the UK. People have been buying direct from us from the UK

Those are progressive springs used on the sides of link car but they are more linear than the AE front springs. The AE springs in theory should be linear due to the constant coil pitch but due to the outer diameter,pitch and length, they are actually more progressive than link car side springs. We run progressive springs on the 1/10th pan cars but they are finer pitch and larger diameter than the AE springs so they are actually more linear.

The reason you want linear up front is because of the lack of weight,super short arm length and for the difference in roll center from the rear of the car. It is extremely hard to get the front of the car to roll even with the rear. When the front binds up,the rear continues its roll and your ride height actually becomes lower in the rear than up front in the middle of the corner. This creates an on power push. To compensate, We stiffen the rear and increase side dampening. The problem with this is with increased side dampening, we slow the reaction of the car down more than it needs. Increased side spring tension will start to effect corner speed if it gets to be too much. The key is to plant the car and let it rotate with minimal force on the tires. This is what i am looking for and in the testing performed this weekend, it showed me that this theory is correct. I really feel that everything can be improved. Alot of things in 1/12th cars have been overlooked for so long and therefor technology has been very slow in this class. I will always be looking to improve.

Heck maybe those of us still running a link rear suspension should be running the AE springs in the rear and the progressives up front Thanks for the explanation...makes a lot of sense.

No problem buddy. This is why i decided to go with rear flextures in place of coil springs for my rear suspension. Little by little we are figuring out the small little details that give the car a great balnce of front and rear spring tension that works efficiently as possible.

BTW,any luck on your project you were working on?
