Continued the work after getting swaybars bushings, brackets, and front endlink.

Unfortunately, the brackets of my exhaust broke while removing it to install rear swaybars. I should find somebody to weld it.

Another issue I got with front tie rod, clearance is very little with my 18 inch wheels.

Contacted SPL and they replied amazingly fast, they told me it shouldn't touch the wheels, but if I needed to get better clearance, I can remove some of the bolt material, up to a quarter inch.

I got the 19" on it to check the clearance.

Rotors have some cracks, I hope it can hold up to the rest of the season, as there is only like 5 events left (2 Autox, 3 trackdays).

Next
modifying the tie rods, don't want to have the slightest chance of touching the wheels at track.
Installing Endless pads.
Taking the exhaust to get welded.
Corner balance and alignment.

The rotors have surface cracks. What you can do is to have the rotors turned 0.010", and then doing a dye penetrant inspection on them to see if the cracks was removed.

Finished the car today, and corner balanced it as quick as possible, didn't try to reach perfect 50%. I modified the tie rods to give better clearance with the wheels. I found out that the car has gone 40 kgs less in weight, I think wheels and coilovers made a difference.

So last trackday was a very great day, it was very exciting, getting 3 seconds off of my best time, and a friend who is getting ready to join tcr drove it and got 2:20.3, but definitely he was going to do sub 20 if there wasn't crowd, and I will work my way out to get it.

My impressions of the coilovers, on street they are very comfy, maybe a little harder than stock, but not harsh at all with soft compression setting. I tried it on an empty roundabout and suddenly I couldn't wait for the trackday. On the track, the front side was very planted and responsive, the rears were bouncy, feels like they are bottoming out, I contacted MCA to check if they went very soft on the rears or there is an issue.







Here I got 2:21.5 in the first lap

Here is the video where my friend got 2:20.3 opt 2:20.2, so I will be aiming to beat his time, currently standing at 2:21.5 opt 2:21.0. He will be going to TCR Europe this season after he dominated the local championship, hope he will do well in his second international competition. He went to 24hr race in Spa before and his team got first.




Also, I found this video for a Cayman GT4 who was following me in my first session, first time to drive my car with the new setup, but I think currently, my car can go head on with GT4s, faster in turns, but GT4 has better power.

very nice! keep posting :-)

Agreed!

Wow, that GT4 driver was all business, loving that dive pass on the GTR. Took him a full lap and the long straight to get through you, you are doing the Z34 a great service!!!!

Keep us posted on the rear coils soft feel. :tup: great driving and videos, as always.

cv, the exit speed was on a different level, I was going to continue behind him, but I have 2 lap limit before the car overheat :shakes head: even with all the work, it is still not perfect in that regard, I will try 50 weight next time.


Madwi, I have been in contact with Josh Coote, the owner of MCA, he is a very knowledgeable guy, he explained to me that soft rear springs are mean that way to give leverage compared to front and to put power down easily. Also, he said it shouldn't be bouncing, but before changing anything, I need to check the full adjustment range. So, until next trackday, I wouldn't be able to give any more feedback, I tried on empty parking lot, with softer setting, it doesn't bounce, but will appear in track if it was bottoming out, which now I think it isn't the case, because it should be bouncing in the street as well, but it was very comfy.

More updates

Getting new BFG R1S in 285/30/18 for Autocross

They are on

Also, getting my seat removed and installed a Sparco Evo 2 US.

Got some issues with the install, as I couldn't go as low as I wanted because the shell of the seat doesn't clear the rails and I cannot use the lowest setting. Also, I couldn't use the rails until I flipped one of the side mounts to clear the seat.

And here is the some photos of the car with the tires, I think I need to lower it more :icon17: but I don't want to do another alignment and corner balance. Rightnow, I am sitting at -3.25 front camber and -2.00 rear camber.

First test for the slicks and seat, it is much nicer to drive with seat support, but not nice to get in and out :bowrofl:


I did an Autox event, sadly I got only 4 runs, and one of them was dump, yes it rains over here. Also, still not able to use full grip of the slicks, because the layout was very narrow.

My best run



One fun experience

Keep us updated on your findings as you get adjusted to them. :tup:

I went to a trackday today, (yesterday if I want to be exact, it is 4:00 AM right now)

The track was dusty, the weather wasn't ideal (around 30C -10 degrees higher than last trackday-),

I tried softer settings on the suspension, the bouncing has been less visible, but still there is some instances of snap oversteer, but I have the big issue of changing a lot of the settings :rofl2: this time I had more front camber (-3.25) and different tires (BFG R1 S 285/30/18)

I felt the tire height is a big disadvantage to me, although the tires felt very sticky, but many variables to get an apple to apple comparison by times, I didn't beat my best time, but I was close.


Some videos from today.
