Would you recommend a sprung disk for a daily driver?
Typically, yes. Though we've used rigid discs on daily driven street cars in the past, sprung just makes your life a little better.

We had some time to really start pushing things with @KTuner today on our shop Si and were very pleased with the results. Denis worked his magic with the help of @VitViper and managed to get some consistent 255 whp and 315 ft/lb tq (later we managed to squeeze out some 265 whp and 324 tq) runs on e25 blend fuel through our catted downpipe. Not too shabby for a 1.5L and thumb sized turbine! We expect to see higher numbers on with a catless downpipe, higher octane fuel and more time getting used to this platform.

Mods: PRL catted DP/FP combo, PRL FMIC, PRL Cobra CA I and E25 blend fuel.

The exhaust is dropped on this video because we wanted to see if the stock exhaust was a restriction and saw 0 gains.

Excuse the cellphone quality here, but incase anybody missed, we managed to squeeze out 280 whp and 335+ ft/lbs tq out of our shop car the other day! Thats 100 hp in gains and well over 100 ft/lbs tq gains over stock with only a few simply bolt-ons and tuning on e25/e30 fuel blend! 100 whp in a car that comes with only 180 whp is a night-and-day difference!

We dumped that cat-back exhaust from the front pipe in the video to see if there were any gains over running a full stock exhaust... To our amazement, there was not! This car pumped out repetive back-to-back 280/279 whp pulls with and without the factory exhaust. The factory exhaust system has showed to flow extremely well for this little 1.5L turbo and tiny turbine so far. With that being said, power gains from going cat-back exhaust will not be notable whatsoever on sub-300whp setups for this platform.

We switched from our catted downpipe to a catless and picked up roughly a 5-7 hp gain. The knock control value actually dropped down to only 49%, which helped us free up some nice power. To simplify, 49% knock control value means that our parts, including our catted downpipe, helped this car pick up more efficiency than we have ever seen before!

To reiterate, this car has nothing special done to it and this isn't a marketing ploy. Any 1.5T 6MT Civic customer can expect to see identical gains by doing $2,500 - $3,000 in mods. :)

How big are we talking here? :)
Probably something like a Garrett 2867 or 2871 to keep response there but still allow the 1.5 to make 400 hp!

We decided to take our 2017 Civic Si to the track and see what it could do.

First hit was 13.3 at 108 MPH and a 2.1 60ft.

Our best run of the night was a 13.1435 at 108.77 MPH with a 2.0 60ft on stock all season tires. This car should break into the 12s with ease when we get some slicks on it!

Are you expecting internals with this kit?
We will see, but hopefully not. The larger turbo should shift torque to the right, which will help save the rods/internals.

that would be beneficial to the CVT too then if the torque is shifted right......Right (actually, say no, my bank account doesnt want to handle that lol)

I don't think it makes a difference on the CVT. Regardless of RPMs, I would think the torque would stress the CVT belt in a similar manner.

Alternatively, shifting stress to the upper RPM range allows each of the four rods to share the load more evenly. At low/mid RPMs, stress is focused on a single rod for 2-3x longer during each combustion cycle.
