Suspension
The spirit of modification
Reusing scrap parts to get the perfect inner diameter!

I wanted to install Swift springs that I happened to get on a KTS coilover, but the Swift spring's inner diameter was too small for the coilover spring seat. So I cut a KTS spring and used one coil as a spacer. It fits perfectly!

A stock Impreza tie-rod end can be reused!

I installed the two-turn knuckles that champion Katayama is rumored to make, and extended the lower arms by 2 cm. I was going to switch to aftermarket tie-rod ends, but a shop told me stock Impreza tie rods would work. They're longer than the ECR33 stock ones.
I couldn't follow what he was saying at first, but seeing it made sense! Sure enough, at the very bottom of the Swift spring there was one…

…coil with a larger diameter. That keeps the spring from slipping out of place!
If the inner diameter doesn't match, this fixes it!

Honestly, I think I'm a bit of a nerd!
There may be many interchangeable parts. He also paired it with an Ikeya Formula tie rod.

You can get a rough idea of the front suspension's behavior through the steering wheel, but I wanted to understand the rear, so I installed an HKS DMR (dual camera) in the wheel well after drilling a hole. Another camera records the in-car view, and I study how much the suspension moves during different driving styles to help with setup.
It helps with setting the damping force. As a result, his competition results have become more consistent. The downside is that tire dust quickly builds up on the lens and makes the footage hard to see.

A determined −9 degrees of camber!

During a track event, my driveshaft boot tore, so I made an emergency repair by wrapping it in five layers of plastic bag and securing it with cable ties. I've had no problems driving since then, and the lighter weight might even make it work better than stock! When I replace the driveshaft, I'll make one for the other side too!
To match the extended lower arms and increase front negative camber, I lengthened the lower arms. I ground off the stock S14 stopper, cut the arm, and welded in a U-shaped steel plate. I finished by sanding the welds and painting the whole thing blue!
Amazing! It sounds unbelievable, but it survived a durability test over 5,000 km…
Comment
Since he's running that setup, this homemade boot might actually work. He really likes it and bragged, “Why doesn't everyone do this?” That's a bold claim…
I was sure a shop had made it, so I was surprised to hear it was homemade. He has no stopper, but he runs the aftermarket tension rod fully compressed, so it hasn't gone into over-center so far.

Possibility!
