Im told maxin out gear ratios is a big advantage (simply because the car dosent lose any speed during gear changing) is this a major advantage???:dunce:đź’ˇ
 
In short, No.

I assume that when you say "max out" you just mean making the ratio really low. (sliding the slider all the way over)
if you max out the gear ratio, you'll (theoretically) have a high top speed, but your acceleration will decrease. On a short track, that's awful, because you don't have room to get to a high speed.
On a long track like daytona or something with long straights, you can achieve higher speeds with a lower gear ratio, and that's useful. But all cars are going to be limited by air drag; when the engine can't push the car forward harder than the air pushing it backward.

The best gear ratio will depend on the track you are on, the car you are in, aerodynamics, and how much power it has. Typically, i set the max speed of my transmission to be just a tad higher than the top speed i reach on a track's longest straight.

Will keep that in mind thanks for the heads up:)
 
I agree with the above help. I also adjust the top speed if I expect to draft the other cars. I can gain another 20 mph in top speed if I'm drafting.

This will help in two ways. First, if the car you're driving (or AI) just isn't going to compete well at it's normal non-drafting top speed and you can't corner better than the AI you can draft and use it to pass at critical times. Second, if you're car is well capable of taking the lead in a straight anyway (Toyota GT ONE, or FGT & X2010) you can use it to see just how fast you can get up to.

I used this in the X2010 to reach 298 mph at Indy. I also used the drafting in the C6 09 Corvette RM to win the Dream Car Championship. Once I was out front I pulled down low out of the drafting territory the AI were taking so they couldn't catch back up.

Setting transmission gear ratios is not that simple. A car for example that redlines at 8000 rpm, but maxes torque and hp at 6000 rpm and drops off both by say 25% at 8000 rpm will benefit both in top speed and acceleration if you set up your gears so you can shift shift at say 6500 rpm. That might mean for example on GVE setting a top speed gear ratio of 350 km/h when your actual top speed is 300 km/h but at 300 km/h you are turning 6500 rpm. If you set your top speed to say 320 km/h you'd be doing 7500 rpm but you'd never get to 300 km/h because your torque and hp would have fallen off as you acclerated in 6th gear up from 6000 rpm. You might only reach 295 km/h for example.

You also have to look how many revs you are turning on the tighter corners. Say for example you have a tight hairpin that if you shift into first you over rev the engine and in second it's down to 5000 of a max 8000 rpm. You will take that corner faster if you can set up your gears so that you can take that corner in first by moving the slider to the left enabling a taller first gear that you can use in that corner. Cornering with the engine revving fairly high helps to pull the car around the corner tighter.

Getting the transmission right can sometimes mean a full second or more per lap on average length courses, more on the longer ones. With some cars it's not as important, those being the ones that have good torque and hp up near the redline. You have to take it car by car and figure it out.
 
Maxing out all the gears isn't a wise idea, but maxing out either the first 2 or 3 (depending how many gears your gearbox actually has) can sometimes be helpful in SOME situations.

If you have a powerful car having long 1st and 2nd gear can help reduce wheelspin (also suspensions settings, LSDs and throttle control also apply here) either from a standing start or from exiting a tight corner.

Many of my cars are setup like this, on a 5 sp gearbox the 1st and 2nd gear are long and the others are 'close ratio'.

6sp & 7sp gearbox - 1st, 2nd and 3rd would be long with 4th, 5th, 6th & 7th are 'close ratio'.

This helps to reduce chances of tyres spinning in lower gears and being close ratio for the higher gears helps the car to accelerate quicker at higher speed.

But, all gear ratio's should be tuned according to the powerband of the engine and top speed of whatever track you're racing on (also take into account slipstream effect too). Check engine power in settings then check your top speed on that track and adjust accordingly.

Some people also like to tune their gears according to track layout and adjust the gearing to suit specific corners.

The choice is yours :)

Thanks fella that makes perfect sense will try it out over the weekend, guess with psn down got plenty of time to put the hours in!!!:grumpy: BUTTMUNCH!! Scary just been watchin Beevis and Butthead on UTUBE COOL:)
 
You can also change the gear rations to fit the corners. Lets say there are important corners taken at 140 km/h you wouldn't want to have a gear change happen right at that speed but maybe a little earlier before the corner or later after the corner depending on the power band of the engine. Change of gear in mid corner migh unsettle the car...
