So let me bring everyone up to speed - i took the leap and got a Midori Seibi Red G Sensor - the more aggressive one
It was very easy to replace for the 32 GTR - direct remove old G Sensor - It comes complete with Brackets for a remove old and plug & play new.
I installed it and went for a Bathurst Supersprint the same weekend - i had issues with my Clutch throw out bearing but i thought it would survive the race - arrived there and did 2 runs down the hill into the chase to end on the straight - finished 21 / 70 cars that day with 2 runs in.
What i noticed :-
Car felt slower coming out - though the times speak differently - its more composed and coming out of bends the car felt flatter
You will notice the Torque sensor moving slightly and in less gains - compared to the on and off from the old g sensors
i destroyed my throw out bearing so i had to tow the car back (pic for reference) lol did a good one.
Lost motivation after this - so i left the car for a couple of months and said - hey lets do it again - Got an ATS twin plate carbon clutch and a new ATS rear diff - got it installed
Headed to Wakie in August - it was a long hiatus
My last session at Wakie was 1:13 dry - then it started raining - last year. The car didnt feel as composed and the tail kept on trying to come out - at the fish hook - so throttle control with the old G sensor was very very sensitive
This August with the new G Sensor - i finished the day with 1:09 before the brakes decided its time for new pads - so that was the quickest i could do with Z222 Hankook RS3 275/35/18 - UHP street tires - with 4 degree weather.
What i noticed :
The car still felt slow coming out of bends - felt flatter that i felt previously at Bathurst and not so twitchy - and i noticed this time is due to the fronts coming in earlier at a more gradual rate (torque meter movement - slow and steady) - making the car feel slow but the fronts are actually pulling you while the rear do the work
i can keep the car with its tail just at an angle - while putting on the power much earlier and just pointing the front where i need it to be - inducing a nice slide out of Fish hook saving lots of time
On the brakes - the car feels flat - not twitchy
Overall i rate them - for being a pure plug and play without any adjustments - it improved the characteristics of the old girl quite dramatically - i personally think - with a bit more control using this G sensor - would make it even more amazing (getting a Ruzic / torque controller mated to this G sensor)
So in my opinion - if anyone wants to go more and prob better - i think the DTMII looks like an amazing choice - or an ETS Pro which i think would be ultimate upgrade.
Either way - if you want a fuss free - no wiring - plug and play = improvement - i do say the Midori Seibi - is great upgrade for the older G sensors of the 32 GTR. It sends its reading a lot quicker and it makes the ol girl so much more lively.
Hope this helps anyone thinking of a G sensor - i have a friend who purchased the latest Tarzan G Box - when his car is out - i will write another review here on it.
