The Evo Garage Mugen DC5 race car has longed for this day, first time out after the upgrade to its suspension, mounts and tires. The old Öhlins came out in place for Mugen N1 coilovers. Alex race mounts were replaced with Hasport billet mounts using the super hard urethane inserts. After maxing out the capabilities of the Yokohama Advan A048, both of the DC5s are now using Hoosier R6 tires. Even though with a wonderful performance, target times were not met this month. Much anticipation will be expected from the Mugen DC5 after some fine-tuning next month.

Prior to, a brand new USDM ITR transmission was ordered. Aside from the 4th, 5th and final gear, it is completely identical to the JDM 98-spec trans. Listed here are the gear ratios for both trans.

USDM ITR transmission gear ratio:
1st: 3.230
2nd: 2.105
3rd: 1.458
4th: 1.107
5th: 0.848
Reverse: 3.000
Final Drive: 4.400

JDM 98-spec ITR transmission gear ratio:
1st: 3.230
2nd: 2.105
3rd: 1.458
4th: 1.034
5th: 0.787
Reverse: 3.000
Final Drive: 4.785

Having the closer 4th and 5th gear was defiantly a plus, however the potential was limited by the 4.400 final gear found in the USDM trans. Solution? That was easy, we replaced it with a 4.929 final gear from ATS&ACROSS. Increased acceleration and response is noticed from this new setup.

New transmission with ATS&ACROSS 4.929 final gear @ 9000rpm:
1st: 3.230 – 63.47Km/h
2nd: 2.105 – 97.38Km/h
3rd: 1.458 – 140.61Km/h
4th: 1.107 – 185.19Km/h
5th: 0.848 – 241.74Km/h
Reverse: 3.000
Final Drive: 4.929
