Suspension, Brakes and Exhaust

Some more major pieces got put in the car the past few days starting off with the Sakebomb Garage FPSport Spec Ohlins DFVs with Swift springs and remote rear adjusters. The major differences between the standard out of box factory Ohlins DFVs and this set are:
  • Custom valving
  • Custom Billet 6061 aluminum lower mounting forks (stronger and lighter)
  • Custom Billet 6061 aluminum top hats with spherical bearings
  • Swift 13kg/mm 6" front main springs with 0.8kg/mm helper springs
  • Swift 11kg/mm 8" rear main springs
This kit normally comes with Ohlins 11kg/mm springs all around but from past experience setting up my S2000s I prefer different springs rates so I had Sakebomb Garage change it for me in my order. I went with Swift springs because they're able to achieve the same spring rates with fewer coils making for a lighter setup.

The remote rear adjusters are nice because it means not having to yank the trunk liners in order to make adjustments once I get to suspension tuning later this year. The only issue is that Ohlins apparently changed the diameter of the adjusters on the newest batches of shocks they shipped so the adjusters that Sakebomb Garage makes no longer fit. They offered to replace it but SJF simply widened the hole a tiny bit in order to make it work. If it works, it works!

To get back to being street legal, Lupa's old Berk 67mm high flow cat and Mugen Titanium Sports Exhaust was installed. You can clearly see the theme here that I'm consolidating all the Mugen goodies into Bumblestook. I think the Mugen exhaust is the best street exhaust made for the car. It looks and sounds great. Under normal driving conditions it's not loud at all with just a slight rumble but when you get it on, it screams.

Since Bumblestook no longer had stock primary and secondary O2 sensors (the Haltech was running from a wideband on the header only), I got some new O2 Denso sensors rather than OEM ones. Denso manufactures the sensors for Honda anyway and it didn't make much sense to spend four times more on OEM when people have been running the Denso equivalent just fine. For reference the part numbers for 2000-2005 S2000s are:

Primary O2 Sensor: Denso 234-4124
Secondary O2 Sensor: Denso 234-4601

I decided that for her normal use we'd go back to stock brakes so while SJF waited to bring over the front brake ducts, new rear rotors and OEM pads were installed.

Finally, SJF did a really sweet job of hacking up the spare glovebox I got to reduce the gutted look of the interior. It covers up the replacement bulk heads and OEM seatbelt reels while still preserving the use of the main glove box and the smaller part of the secret compartment. It also means the 12V outlet and trunk release are in their stock locations. Coincidentally, reinstalling the glove box means I'm also able to reinstall the Modifry camera mount. The sides are open for now but we're thinking about using a sheet of painted lexan to tidy that up a bit more.

There a lot more work left before she'll be where I want her to be. On projects like this things tend to evolve a little as you work on the car and additional things to fix or improve upon while the car is under the knife but so far the vision is starting to become a reality.
