Okay, here's what you need to do. This is a setup for the route X speed test. You need to fully uppgrade it, and have the following setup (or something like it, I'm away from my PS3 right now.)
40/-25
5/12.6
1/10
1/10
1/1
0/0 cambre and toe.
For the transmission, you need to do the following equasion.
(max power RPM)........(what top speed you want)
------------------- = ------------------------------
(max RPMs)............... (this will be the top speed in the transmission tune)
You need to do the following equasion, just replace the RPMs with the random numbers that I'm putting in. Again, I'm away from my ps3.
After you fill in the equasion, it will look something like this.
6000 ....210
----- = ------
9000 ... (n)
Please note that the end marks in those equasions mean nothing, they are just being used to seperate two numbers, because they were glitching out.
Cross multiplying from this equasion we see that 9000*210=6000n. 9000*210=1,890,000. 1,890,000/6000=315. Using this math, you can calculate the top speed that you need to set on the transmission menu. This will put the max power at whatever speed that you put into the equasion. You may have to do this a few times with different top speeds put into it in order to get the actual top speed, and the car may not be able to make the corners at SSRX. You can mess with the other settings all you want. Maybe aero in the back helps the car reach 300+ (for example, a GT-ONE). Whatever works. If you find a better suspension tune that works almost as well when it comes to top speed but lets you take the corners at SSRX, que me in so that I can take a look at it.
This has been JJSCHMITTY's guide to top speed tuning.
