jpowersjr2 - I thought about it and just went with a new arm. The new arm solved some of the clunk. I wasn't comfortable with spending so much money on 2 bushings but no solution for the ball joint that joins up with the spindle. The sound from the trans bushing drowns a lot of the other NVH out. I did go with the SPL tie rods that dialed out the steering dead zone.
So you replaced it with a new OEM one? Which SPL tie rods did you get? Sometime I feel as if I have some sort steering issue, like it wanders I feel like sometimes. Not sure if it's just me.

Yup, a new left lower arm.

I got these:
Bumpsteer Adjustable Titanium Series Front Outer Tie Rod Ends for Nissan R35 GT-R

With steering issues, I referred to my alignment guy's feedback. He mentioned the deadzone which I felt too and went about solving it through the process of elimination.

24hrs worth of labor later the supercharger is in. Thank goodness I did it on my own otherwise the total cost would have been painful. Most of my install time was spent test fitting and figuring out the best routing for all the tubes, piping, and wiring. There was a lot of deviation from the instructions but nothing that would impact the operation of the kit. The instructions claim that some things are pre-assembled, like the bypass valve, but that's far from accurate. All the tubing had to be cut to fit so that there is clearance. There was some triming of the air diverter that needed to be done to fit the heat exchanger and charge pipe.

I would definitely not recommend novices attempt a DYI.

Next steps are road testing and tune via UpRev.

I have great friends

I did maintenance to dial out the play in my steering some more and to lock in my alignment changes. My friend decided to give me a hand and add some "decals" as you will see in the last picture.
  • Added SPL tie rods
  • Added SPL rear mid-links
  • Added Swift springs 65mm ID, 12k spring rate, 6" length.








I also roasted my brakes at the last track day. I came off track with the calipers measuring 850 F. Needless to say, the rubber dust boots were toast. Thinking myself handy, I attempted to rebuild the calipers. This didn't work out at all since I sheered off a seized bolt that held the rear caliper together. I ended up ordering a set of remanufactured PowerStop "Akebono" calipers. I'm still wondering if these are Akebonos since the Cardone remans have the embossed Akebono lettering casted on the housing of the caliper, yet the PowerStops did not. I'm not too fussed since they fit and function fine. Just a little sad that my original calipers are gone. And once again, my friend decided to "help".

Yeah I was wondering the same thing! Looks like it's off the ground, is something disconnected?

Good job on the brakes and LOL at the "Brembo".

What do you think of the SPL tie rods? I have thought about getting them for my car as well.

Great question! I thought something was off at first, but it is how the spring sits unloaded. Everything aligns once it's on the ground. SPL went to great lengths to emphasize this in their install manual (Page 4). Link

I do sometimes hear the spring re-seat itself when I rapidly shift lateral weight (loading and unloading). Some guys go the extra mile and get a helper spring to help make sure that under extreme unloading the main spring doesn't eject itself.





As far as the tie rods go, I love em. The car is extremely responsive to steering input. I have my front ever so slightly toe in for the streets, but I have to be on top of my steering control. The kit also comes with shims of different thickness to help dial in or out bump steer so if you're lowered, you can play with it.

I'm almost full SPL at this point. All I have left is the front lower control arm bushings, which I've said that I'm not doing since it's not a complete solution, and the rear knuckle. Probably going to get a pair of rear knuckles from a wreck and build from there since I'd like to do my rear hub bearing at some point too.

Amazing progress, would love for you to give feedback on temps all around once you're up and running.
That front end is pretty populated, I'm pretty sure you'll be fine however I think your front end real estate is close to maxing out.

Have you tried maybe moving some of the coolers to the side by the fogs, possible future idea?

Crawling in traffic. It was almost 90 outside. VVT temp is oil temp at the heads.



I have plans for the fogs. Brake ducts are a project I keep stalling on. They will be routed there.

Titanium brake shields came in. Hopefully I'll get some more life out of my brake piston boots and keep the brake fluid from boiling over.
