So after the first front Koni Race Insert, we took away some changes that needed to be made. First the collar nut needed to be machined right so the strut didn't blow. It also needed a softer bumpstop, and trimming it was not a good idea. So this time around we fixed that. Very pleased so far. Rides much better and feels like my friends Ground Control Equipped E36. So super happy about this so far.

I took it on the bumpiest most pot hole filled back road I know. It did fantastic, car didn't get upset. My girlfriend filming bouncing around on the worn comfort seat springs she was a bit upset.

At this point, I have probably spent more then just buying Ground Control and being done with it. However what is the fun in that?

Should be a bigger update soon when my 35mm pics get developed on Tex Fest/other roadtrip.

Great video. I dig watching the tags hanging from the mirror swing and sit sideways with the centripetal force. Pushing that car.

So recently I bought a film camera. Wanted to teach myself about photography, so far I have learned a lot and still a lot more to learn. There is also a novelty to it I like. My friend got a Nikon FM and I got a Olympus OM-10.

First trip we went to Austin, just set the camera to auto with some Fuji C200 and Kodak Gold 200

I shot some Portra 400 and 800 and wasn't happy with the colors. I think this is due to the lab

TexFest was an adventure. Car did fine but was a LOT of driving. First we left Thursday night, got there to meet a guy who had a M60 swapped E30 that was broken (ektachrome 400)

1000 miles in that bucket seat is quite tiring. It was a great weekend, hopefully next year I can document it better. I did not have a tripod at this point.

I got one though, and learned that is my favorite time to take pictures is at night:

Haha. I love it. I’ve been thinking to do the same. I’d love to develop film as well.
It’s tricky getting colours right at night with street lighting.

So car has been open diff'ing. Swapped a healthy S3.46 into dads car. Rebuilt his old diff with 250k on it. We thought it was healthier then it was. So I ordered 2 clutch packs from FCPEuro, and I had a S2.93 parts diff with super nice clutches. Used the best one for my 3rd clutch and its dogplate. Reused/flipped the dogplates and then reassembled. It has been one of the best things I have done to the car. Very happy with it, other then it is leaking a bit. Had the new sideseal orings, but didn't install them like an idiot. Luckily just weeping, no drops on the floor.

[LeiseyJr]

Did a trackday with PCA was good to finally be back at a HPDE. Car did great, the new 3 clutch diff feels super good. The Toyo RA1s are also very nice.

Gave some modern porsche hell and the olders one too

This weekend I went without the ghetto catchcan, so I had to leave it in 4th through the slow section of the track, good way to practice carrying momentum.

Really Proud of this pic:

Great photos.

Was the diff upgrade as simple as remove and replace the clutch plates? And what's the biggest advantage you have seen-- you mention it as a great upgrade but don't say why...

Yes there’s a 4mm space you remove and add a clutch disc/dog ear in its spot. They do wear a bit uneven but it’s cheap and easy enough to do.

I have noticed a lot more rear grip on corner exit. I thought the car would slide more but that is not the case. Actually using traction of both rear tires on corner exit, and car overall feels more mannered. It just made it way easier to drive. When I try to drift the car now when it is wet also no random one tire fire, both tires stay locked all the time.

On a mostly street oriented car that has street tires, I don’t think the upgrade is necessary. Just fresh clutches should be more then enough.

[Tiit]

Nice pics.

[LeiseyJr]

Made my own eprom today. Happy about that.

[LeiseyJr]

Nothing much has changed. I installed a Euro ecu with a correctly adjusted AFM car likes it.

Had another track weekend. Had a lot of fun. It was raining Saturday and I was on really bad rear tires (heat cycled and low tread), so really interesting.

https://www.youtube.com/watch?v=Qthrko_S9aQ&t=62s


Sunday it dried out and had a lot of fun. I did miss a session because my key fell behind my grill, when adding oil. That took 30 minutes to figure out.

Finally decided to trust my EPROM for a full track day day. Car did great ran all 70 laps without a real issue,

Only issue is the rear (shit reman driveshaft) u-joint is squeaking (was doing it before the track event) and y pipe fell off. Engine is still moving a bit too much.

Car has cost me a lot in consumables, which is killing me. Tires, brakes, etc.

Tire wear is Excellent, but they are dead so was a slidey weekend.

What’s your current suspension setup? Is camber adjustable? Roll centre correction?

TLDR
Stock Geometry (no roll center correction, no eccentrics).
Camber Adjustable in the Front

Glad someone is enjoying it.

After last event, I broke the diff mount, and screwed up the rearmost U joint on the driveshaft.

Jay was kind enough to send me a new to me diff mount. Thanks Jay!

I cobbled together two driveshafts again.

Car survived an auto-x. Really happy with how it did, competitive against an e30 with a s52.Hopefully next time with fresh tires and or a drivers mod, can match his time.

My tune:https://www.youtube.com/watch?v=2TmRgFjM3SA
Stock 061: https://www.youtube.com/watch?v=VXCi0y_jaxA

Dyno'd!!!!!!!!!!!!

So I compared my chip tune to the stock euro tune. Those are the best of the 4 runs, two runs for each. Was pretty consistent, my tune more so.

+16 whp and +10ftlb for the peaks. The power under the curve is higher everywhere.

Assuming 15% drivetrain loss that is 230 crank hp with my tune and the stock euro ecu is 208 crank. A little upsetting to see it's less than 218 with stock DME but with 98 ambient the DME is probably pulling timing.

Torque Curve is healthy, but will need bigger valves to have less of a taper after 6000.

[Tiit]

Solid gains. Are the gains in ignition timing?
