Nice! FI HFCs are pretty expensive but you can’t argue with that sound quality. I’ll probably place an order soon — this rasp is killing me.

 

I bought them for $550 shipped, used, on this forum. He said roughly 1000 miles on them.

 

I’ll be on the lookout. I wonder if I’ll need a retune if I install these...

 

Added this last week. Wasn’t expecting much but I can definitely feel a difference in steering tightness at the limit.

 

Went to Island Dragway this past Saturday. Car ran a 13.51 @ 103.7 MPH. Conditions were 67 degrees F and 74% relative humidity. I couldn’t really hook for some reason. Other people were having the same issue — guessing the track wasn’t sticky enough. Either way, the corrected time using a DA calculator is 13.416 @ 104.981 MPH. 🤷🏻‍♂️

 

Any updates on track performance?

 

Oh yeah, with the X, that thing helped a lot with the understeer.

 

Haven't been to the track since last time. I had the transmission rebuilt and replaced the battery and alternator. Still need to replace these test pipes as they sound like **** now. I’m going to Island Dragway next week. I’ll update the thread soon.

 

I finally decided to install the Grom Vline2 that’s been collecting dust on my shelf for the last 1.5 years. Works great. Best part is that it’s wireless CarPlay.



New steering wheel and shifter installed as well:

 

Very clean look. By far the best steering wheel cover I've seen so far.
We share the blocker that prevents everything from disappearing between your seat and the console

 

Where is the steering wheel cover from?

 

What gets me is that you have CBE, CAI, and test pipes but only run 13.51 or with a corrected DA 13.416. Are you running a full tank of gas during the runs? I have a G37X coupe which is a bit heavier and only has a K&N air filter drop-in, a test pipe with a muffler delete running 13.44, and a corrected DA 13.368.

 

Ran recently and did a 13.4 @ 104.5 MPH. Best so far

 

Thanks! That thing is useful.

 

It’s a stock wheel from the dealer.
