Even better if its for an auto twin !
Perfect for max acceleration on our local racetracks without overrevving on the highway.

2. rebuilt axles w/ Redline CV grease, vented boots.
3. replace 4.1 diff with 4.3 diff from a 2017
4. rebuild coilovers w/ new bumpstops, lube bearings, etc.
5. whiteline front bumpsteer kit
6. Front camber bolts to get just a lil more grip out of the front end.

This weekend's fun:
1-6. Finished all the details in the above list.
7. Installed new Accusump
8. Changed the oil
9. New trans fluid


.........
Tonight's after-work fun is setting up scales to do alignment and corner balance.

Verus Engineering all the things!







Been a bit of a process experimenting with all the variations of Tiffany Blue out there and these RPF1 inserts were worth the wait. revlimiter.net is a new kind of perfectionist.

Does this basically make the engine spool up faster, having a better ratio? Is the difference noticeable vs. the older 4.1?

I hit my front lip at the parking lot last night, so check to see if it broke or not. Thankfully didn’t broke off or have any crack.

spool up faster? depends on what you mean.. but yes, the car will accelerate faster in each gear. For the same vehicle speed, you'll be at a higher RPM and these engines make more power the higher they rev. so the faster you can spin it, the faster you'll accelerate.

in my case, it comes down to gearing and min corner speeds on track. There are a few corners where I'm down to about 50mph. that puts my right at the top of 2nd gear (two more shifts in the turn), or bogging at 4500rpm in 3rd- below the power band.

so with the 4.3, I'll be roughly 4700rpm at the same spot on track, a little higher in the powerband, and a little more power coming out of the turn so I get back into the power band quicker.

At the end of the straights, I was hitting redline in 4th about 2-300ft before the braking zone. instead of holding it at the rev limiter, I'll now have to shift to 5th well before that same spot and I'm hoping it will reduce lap times and strain on the engine running it near the rev limiter.

Finally got this puppy on:

Got my flex fuel kit installed. Went to grab my laptop to load the new tune and do some logs, but the laptop was dead. So now I'm just waiting for my computer to charge.

1. Installed whiteline stabilizer bar bushings on the front bar. While I had it apart I sanded/wire brushed and painted the subframe brackets.

2. Installed a 949 steering column spacer. Fought a protracted battle with the horn wire. Ultimately made a short jumper wire.

The front end seems more planted - the OEM bushings are surprisingly soft which, I suspect, changes the weight shift dynamics. In another thread a member used the term linear to describe the difference. In a nutshell, that's it. The handling seems more linear - less waiting for the suspension to settle. Worth the time and effort.

The steering spacer has been on my to do list for a couple of years. Finally, bought one and installed it. For the freakishly tall among us it's a revelation. With the stock set up, to get the seat far enough back to fit my legs and reclined enough to accommodate my melon, I'd be stretching my arms to reach the steering wheel. A couple of observations, 1. the added two inches makes the turn signal and wiper stalks noticeably farther away. Not a big deal - big hands usually accompany general largeness. The added distance puts a serious stretch in the horn wire. I battled my for quite a while and ultimately admitted defeat and fabbed a 2" jumper wire. [949 guys - including a short jumper would help those of use with big clumsy mitts] My only issue is the steering wheel is slightly cocked - about 2 to 3 degrees to the left. It's far less than a full spline's worth. It's not a big deal - I'll get it sorted at the next visit to the alignment shop.

I feel like my eyes are deceiving me but did you shave off the 'mustache' of front bumper? It looks interesting. I also noticed the side marker light is in a different place unless it's a reflection. You have any more pics of the front?

No your eyes aren't deceiving you. Yes, my bumper shaved the mustache... along w park lights & replaced the grill mesh. I was gonna do photo on member journal, but winter hit early at my place, so couldn't do good photos. But here are few iphone camera photos.

Front


Side Lights Off


Side Lights On


Some non-automotive fan thinks some coupe Tesla... yes, cuz Tesla make ICE cars

As for the park lights, I got it shaved and installed one of 3 series park lights from eBay (F90 iirc). Bought the smoked version, so in the daily time, it hides it well.

Off


On


Local member say, it looks like next gen BRZ park light... BUT I did it first, so they copied me!

Hope that answer your question
