More updates from Tommy Kaira this week, hot on the heels of their Ebbrezza-R global product launch they’ve released pricing on the version 2 kit. This kit will feature the exact same aggressive design as the original Ebbrezza-R GT-R we got our first look at earlier in the year but will be feature key pieces fabricated in FRP to drive down the overall cost.

You may recall that Tommy Kaira have recently switched their marketing strategy up so that customers can purchase any individual piece of the kit they desire, but they also make available groups of parts in sub-kits on top of the traditional full kit.

For the Ebbrezza-R GT-R Version 2, customers will notice that the following pieces are now made from FRP:

This brings the prices for the kit down overall a healthy amount, for example, for the Front Style Kit which includes the Front Bumper, Front Under Diffuser, Front Lip Spoiler, Front Grille Cover, and Side Ducts you’ll pay just 525,000 yen. Thats down over 100,000 yen versus the version 1 kit.

The price savings grow when you look at the Full Ebbrezza-R Aero Kit though which is down to just 1,260,000 yen in Japan ($13,950 in the US). A saving of 420,000 yen versus version 1!

Combine this with the new global distribution partners and I think we’ll see a few more Tommy Kaira Ebbrezza-R GT-Rs globally shortly!

On the circuit and even with some hard street driving, GT-R owners will know that the transmission temperature has a habit of rising quite rapidly. To compound that, on the GT-R, the transmission is integrated with the rear differential housing and because of this, heat energy is freely transferred between them.

In Nismo’s testing experience, with their Tokachi 24hrs race car and their Super Taikyu R35, cooling the rear differential has been surprisingly effective at lowering transmission temperatures. So much so that they’re now releasing their in-house developed rear differential cooler as a kit for the GT-R.

The kit features a electric oil pump, braided hoses, cooler core, and wiring harness for automatic or manual in-cabin operation. When installed it increases the diff oil capacity by 2 liters which is a help by itself.

In Nismo’s testing of the ClubSport GT-R on Sodegaura Circuit in Chiba, they were happy to see the diff oil temperature at no time exceeded 140 degrees C. Exactly what the transmission temperature was like during the testing is not known though.

The diff oil cooler is due for release in April and we will have availability details at that time.

More from the guys at Gruppe-S today. This time they’ve documented the completion of their custom transmission mount for the G-Force 4-Speed dog box. As you’d know the GT-R’s rear mounted trans-axle has absolutely nothing in common with the engine mounted G-Force tranny so you could have foresaw the problems they’d have bolting it up.

Out came the welder and with a lot of hard work and effort the guys have put the problem behind them by fabricating a heavy duty support structure that should hold up to the stresses of drifting. As a result, the transmission is officially mounted in the car in addition to the engine which was mounted up last week.

What the guys will do with the rear subframe now there’s no transmission in it is going to be the next chapter in this story I’m sure.
