Some foreshadowing, still winter here.

A lot has happened since the Yurkan 6 point cage install. Probably a top 5 mod of all time for this car, the rear and is literally paper mache from factory. Im gonna say regardless of your use case this is something everyone should do (options for fold down seats or not, modular or not as well). I can liken the difference to going from oem seats to nogaro buckets, it's that apparent and that good. If you track do this instead of a bolt in cage.

In the quest to make this car more capable on track the other weak point was the RB brakes, I had out grown them and managed to get a PFC ZR45 kit from a good buddy. The pros is increased brake feel, imo brake thermal capacity, caliper rigidity and pad depth. Also lost a few pounds front and rear, the RB setup was still surprisingly light. PFC rotors are V3 and the rear passenger clunks like an Indian tukuk. I think the specific rotor hat may be tired all the other rotors are quiet.

Braking performance at the track is considerably improved. Above all consistency in pedal feel, brake pedal went up. Overall very happy. Using PFC11 pads and Castrol SRF.

The next big performance mod came to the rear axle. The Fat Cat Ultimate Stage 3 was an amazing addition with 400lbs / 784lbs rear springs. I wanted to correct the rear geometry to allow the rear ride height to drop more as well as the front (but not as drastic). Enter MRT full rear bushing set and and front outer tie rod ends. Rear knuckle bushings (45mm) were eccentric as well as the rtab (60mm) bushings. RTABs were accompanied with anti dive RTAB mount and I think this is the main reason for the drastically increased grip. Install is a giant pain, you need special tools, pullers pushers etc and at least two pairs of hands. For the front you will need to use E90 inner tie rods as they are longer, went with the +\-20mm variant.

Track mechanical grip is drastically increased. This is apparent everywhere. At Mosport GP it felt like I was driving a cup car without a wing. On 265 RE71RS managed a solid 1:33.2 and can probably dip into the high 31s with more seat time and setup learning. There's a lot left in the car but the weak links are the rear axles, oem 270km old diff, and transmission that now doesn't like to go into certain gears at certain times. The goal is to get this car on 200tw tires to hit 1:29.xx on Mosport without aero and the interior trim level of just buckets and rear seat delete. Lofty goal since Mosport is a very high average speed track, but I'm pretty confident I can get there.

I also drive the car on the street, personally I love it, since the dream was always to distill the essence of the chassis and the engine to as raw a degree as I can bare. And the most recent mods particularly the bushings may be where I stop in terms of harshness, it can be a bit too much at times.

TO DO List before year end ideally:

• Construct a light but aesthetic rear seat delete
• installe CSL door panels and delete door side airbags
• replace the rear window trim FFS
• Unlikely: Radium catchcan, Radium fuel rail, Bosch ev14 550cc injectors install. Would require a tune and the funds for this year dried up March 10th.

PS: will post Pics later

My exact experience as well. The difference the 6 point brace makes is insane. I don't track my car but still the difference even driving on the road is huge. I appreciate not everyone can stomach having a brace taking up trunk space, but imho anyone who can should have this. Definitely in my top 5 mods too.

Cool, I was considering building a rear brace myself but now you convinced me! I have CMP topside front/rear so I will use the threaded inserts in those beams
