AMAZING! from the very first press, I was impressed. when driving with abs off, the spring is perfectly tuned! The first progression drops nicely to just about the point the tires break free, and there is just enough press into the second progression that you know when the tires will break. The balance is nice and the strength of the spring is on point. I had some hesitation. I wanted a load cell, as I figured a spring was just a spring, and that the load cell would be more accurate and realistic. Then I read some reviews about how there is little movement in a load cell, which sounds quite unrealistic. Then I started reading the reviews on this thread (well, the other thread for this) and else where. Gotta say, the one big thing that made me pick this over the Nixim, is the way Nixim highjacked this thread, and the fact that there was more bad reviews for it than the GTEYE. Glad I did! This thing is worth the 30 bucks! only the rig I built was a better investment.
So, with the praise of this great mod out of the way, here are my test finding:
I used a track that I am most familiar with, Special Stage Route 5, and a car I know as well, the RE- Amemiya FD RX7. I did a couple of warm up laps to stretch the ol legs, the proceeded to do 5 laps. All aids where off, and the track edge wet yada was set to real.
First five laps were with ABS on, and brake balance at 5/5, second five where with ABS off and 5/5 BB, for the final 5 laps, I did ABS off and brake balance set to 5/2. First the test was run with the old spring, then I installed the GTEYE and other springs in the other positions.
Old Spring lap times New Spring lap times
1: 1:30.254 1:30.345
2: 1:34.153 1:30.591
3: 1:31.502 1:30.273
As you can see in the second tests, there is a significant difference in time, hitting just .34 shy of my times with abs on with the old spring, and nearly 4 seconds faster with ABS off compared to the old spring. Not to mention that I was nearly as fast (if I had turned another lap or two, I would have broke 1:29) without abs and my brakes tuned as I was with abs! This is HUGE. I honestly think with another few races, I will be much faster and consistent with the new spring without abs than ever I was with ABS and the old spring. It is really amazing, this spring.
Not sure that I liked swapping the other springs around though. I'll have to do a league night to really get a good feel for how my legs will feel after a couple hours of racing. though some shoes may help.
If you only do one mod to the G27, this IS the one. If you have a g27 and do not want to mod your wheel, BUY this mod! Hands down the best going for this wheel!
