Проект достоин уважения,тем более сарай,наверное в РФ он единственный,но мне кажется что на 2.0л недостаточно момента для карсивого скальжения,2.5л блее моментен,но и геморнее в плане живучисти,но это так мысли в слух.Еще немного смутил подрамник из швеллера (без обид) вот по этому видео можно посмотреть как сделали задний подрамник в JUN для своих imprez

и вот еще одна интересная статья.

Although we have reinforced our D1 Imprezas with many beefier parts to withstand the massive 500-plus hp our cars make, I am simply going to talk about an easy RWD conversion that can be done by everyday Subie drivers. Most Subarus I see at my Ebisu Circuit are RWD-converted GC8s; however, the conversion method is the same for the GC, GDB, and Legacy.
The easiest way to convert your car to RWD is to remove the front drive shafts. This will lock the center differential and the car will then be RWD. You could remove the front differential, but then you would need to seal the transmission where the front drive shafts would be. Also, the speed sensor is driven off the front drive shafts, so for a simple conversion, the center diff and drive-splines for the front axles should be left in place. Also, the front drive splines on the wheel-side of the half-shaft need to be retained to maintain hub intergrity. These are the basics of a RWD conversion. You should now have a RWD Impreza!
That's not all!
You can drift by doing what I described above, however, because the Impreza's suspension was designed for an AWD car, the RWD-converted car will not react and handle like the RWD-based car you would buy from the dealership.
Below are our secret recipes we found for tuning the suspension. These made Team Orange champions! It took a while for us to discover these secrets, and I will only tell them to my Subiesport readers.
First of all, let's talk about handling characteristics.
Because the Impreza is an AWD-based car, it doesn't have much caster angle like a RWD-based car. In particular, Subaru's caster angle is near vertical. When you drivt with near vertical caster, the steering wheel won't re-center itself. It seems that Subaru's steering re0centers itself in large part due to the front part of the all-wheel drivetrain, which is lost in the RWD conversion.
You will need more caster angle to correct this behavior. First, you need to replace the attachment of the lower arms to ones of pillow ball type. You also need to stack some washers to move the lower arms forward along the body. By doing this, you will increase the caster angle, and the steering will re-center a little more.
Next, I will talk about the upper mount. This is an important aspect in improving the handling, and it will affect the caster angle as well as the camber angle. Usually, when you have a pillow upper mount, you can only adjust the camber angle, right?
But based on what I said earlier, you can increase the caster angle by moving the lower arms forward. With the pillow upper mount, you can increase the caster further.
For those using the GC coilover kit, you will need to change [the mount] to the ones for the GD. For those who are using the GD coilover kit, replace the pillow upper mount with that of the GC. In doing so, you can adjust the caster angle even more, and you will improve the handling a great deal.
Let's talk about improving and increasing the steering angle for drifters. This is most important. There is a method for fabricating a new knuckle, but unless you know what you are doing, I don't recommend you do it! It's too dangerous. There is also the common method of putting washers in, but you can't do that with our Impreza's since it will certainly destroy the rack.
What you really need is a rack from a FWD Impreza (it varies with model and year, so be sure to check first). Amazingly, these racks have more steering angle! I guess that Subaru made them like that so that the OBA-CYAN (grannies) can easily make U-turns on Japan's narrow streets!
By replacing the rack with one from a FWD Impreza, you will now have a more aggressive steering angle. If you open up the holes a little more insude where the tie rods attach to the knuckle, you will have the Team Orange setup. Am I telling you guys too much?
With these basics of front handling setups, you are now ready to dorifuto like us. However, there are smaller detail setup changes you can make. I thought that if I told you too much, maybe it wouldn't be as fun for your project, so I won't tell you anymore for now! But if you happen to get stuck with your RWD conversion project, I can probably help you more in a future column. In the up coming issue, I will talk about how to increase rear traction, so stay tuned!
Удачи в это сезоне.
