Few pics of the bumper brackets, coated in Zinc galv
Inner boot floor, Had very superficial surface rust around there, so took the sound deadening off. Flaked off the top layer then again used chemical to remove the adhesive. Removed the rust with wire wheel and then coated with Hammerite rust beater again ( sadly no pics of this )
My favourite part! the back boot panel, rear inner arches and any area that experiences road rash had a liberal coating of Underbody Schutz type stuff. Not like your usual Bitumen based stuff as it's oil resistant, layered up it also acts as sound deadening.
Drivers rear arch. Any overspray was removed with solvents later on.
Passenger rear arch.
Then final coated in Silverstone silver. Looking much fresher now! and hopefully a lot easier to clean in future.
Part 5. The floor. Where the more Terminal work took part
All the grommets were removed, 90% of original underseal removed to ensure there was no rust hidden. Sadly there was! Front drivers side jacking point was terrible. I suggest you all check yours out, didn't look like there was much but turned into this. There are 3 layers of 1.2mm thick steel. 2 of mine were gone. Luckily the main jack plate was sound. The duck tape was a masking line where I flashed back the underseal til I found good metal. From there backwards she was coated in Hammerite rust beater again.
Due to the nature of the work, it needed to go on ramps, mate of mine not long opened up a shop so it was left with him for the day!
Sadly whilst this work was carried out, I fell really ill with food poisoning and was a write off for a week So only have a photo of the after work, still not right now!
Still mega chuffed with the result, even managed to retain the factory grommet hole, not the best of photos I appreciate!
That's it for welding ( thank christ ) Then both passenger side and drivers side were underbody schutz'd. The sill lips were given a coat of silverstone aswell. Looks so much fresher now and hopefully good for many years to come
The main reason for this work, was to inspect the transmission for a really, really annoying rattle on deceleration. Not your usual clutch buzz. So off with the box and it soon became apparent what was up.
CC release bearing on the left, OEM/Naachi bearing on the right. The broken retaining ring was wedged between the pressure plate and friction disc. Moral of the story, always used OEM release bearings. Fast forward a week or 2
After a bit of shopping around, ACT pressure plate, OEM FCC friction disc, OEM release bearing, OEM pilot bearing, and resurfaced flywheel. Flywheel had a fair few hot spots on it, plus it used to judder when pulling off a little bit.
Then it was box on, supercharger back on, then outside for her first drive, mainly to try out the new rear brakes. Few little things I discovered such as steering column splines weren't lined up so it was 90 degrees out, The laptop not communicating with the EMS ( left a fuse out ) the rear brake pad shims catching on the discs. God it felt good to be back behind the wheel. Clutch is absolutely perfect. Little weighter than OEM but so buttery smooth operation. Then it was MOT time, suffice to say she passed haha!
Thats it for today. More details on the rear brake kit tomorrow work pending!
Done this purely as Preventative maintenance. As I plan on doing a few more track days to preserve the rear hubs and bearings. At N/A tune I seen tempertures of nearly 300c without ducting, 220ish with ducting on track days. So I dare say it'll be a bit more now with boost!
The old curved slotted solid disc vs new vented slotted disc.
Size difference
Old
282X12mm Discs
89mmLX38mmH pads New
322x20mm
Lightweight alloy centre bells with custom etching
Uses Mazda RX8 rear caliper
105mmLX43mmH pads
Did have some photos of the RX8 Pad against the S2000 as there is quite a noticeable difference in size!
As it goes I am putting some miles on OEM/ADL blueprint RX8 pads and feels very good so far on the road, Pads appear to be holding up nicely, not seeing temperatures anywhere near what I used on the road to but yet to test them out on track. Braking bias looks like it's unaltered too.
41mm S2K vs 43mm RX8 off the top of my head mate? Can always run a lower coefficient pad in place. I am trying these out first, then will try some other performance pads.
Wow great work dealing with all that nasty rust
The brake upgrade is also very interesting, are you using standard sized RX8 brake pads? I think the effective height on them should be 53mm.
This setup would then be 23% more rear biased than stock, so probably not ideal to run without a front BBK to even it out.
Whats the caliper sizes on your front 330x28mm kit Tom?
