Seems about right. Do you think those FI 2.25" piping is holding you back?

Yeah I do but probably not by much. I would guess less than 10whp.

I do wish I had a 2.5" exhaust though.

I second this as well. Try softening up your dampers settings first. You may also want to confirm that the dampers you are using are '1' for the softest and '16' for the stiffest. I used to think all dampers started at the softest setting until I put a set of Intrax Racing coilovers on my Porsche and they start at '1' for the stiffest setting and get softer from there. Leave it to the Europeans to do something opposite from everyone else. LOL

I also agree that 10 kg/mm and 8 kg/mm for the front and rear respectively are a little on the soft side. I was an early adopter of the JIC coilovers for our cars which used 8kg/mm springs in the rear and they were way too soft and sagged considerably when I had someone in the back seat or anything in the trunk. I ended up having a custom set of 525 lb/in (~9.5 kg/mm) springs made for the rear, which ended up being a near perfect compromise.

Thank you all. Will confirm damping adjustments and back them off. Appreciate yall.

Today I will be adjusting the parking brake and trimming the rear dust shield to look better.
Also installing a resonated Y pipe to tone down the megan 3inch single. Momma and baby dont approve of the cold starts before work lol. Also neighbor lady has mentioned elvis fell off her Mantle one morning i told her the car was all stock Mt Rainier must be waking up haha.

Put my HFC on today. Installation was going GREAT until the last bolt which was stuck - then rounded off. Took 4 hours to get it off..... didn't expect that at all.

(Yea the bottom of my car is pretty rusty now )





Also replaced the driver side heater hose coupler. I literally touched it and it broke, If you have a higher mileage / older G CHANGE YOURS!

side questions:
1. how's the ride been for you on KYB / eibach springs?
2. so what exactly is your exhaust setup now? HFC with tanabe axleback but otherwise stock piping?

Z1 Heater hose coupler
https://www.z1motorsports.com/coolin...e-p-11190.html

The ride is pretty good, it only starts to get annoying on really bad roads. But i've had these in for like 3 years now and I still like it.

Exhaust setup:
Kinetix HFC > stock midpipe with 12" vibrants welded in place > tanabe axleback
