@Kawa This is the one I message you about probably 6 months ago. Drop me a PM and I'll ping the page over to you to drop onto LG

Only got a couple of default boxes in so far, will do the rest shortly but should help people choose their tyre sizes

About bloody time!!

Hmmm, have you put your max rpm in?

Mine comes out as all zeros too. I don't know my max RPM!!

*Edit, I'm guessing mine's 8500 RPM. Does that look right?

get up, put some shoe's on, grab the car key, go out to the car, start the engine, let it warm up, take a small drive to ensure the engine is fully up to temp, stick it 2nd and bury you right foot until the needle stops! then you'll know your red line!

M2T4

First gear top speed 36.0 mph
Second gear min VTEC speed 39.8 mph
Second gear top speed 60.5 mph
Third gear min VTEC speed 57.9 mph
Third gear top speed 88.0 mph
Fourth gear min VTEC speed 75.3 mph
Fourth gear top speed 114.4 mph
Fifth gear min VTEC speed 95.9 mph
Fifth gear top speed 145.7 mph

corrected final drive 4.319

Ride heigh change -3.8 mm

seems pretty accurate to me

no idea about 5th gear top speed though as i'm still limited to 112mph

can you work out a theoretical 0-60 from this?

not without the weight of the car!

Ride heigh change -25 mm

Why does this change? Mine's at stock height.
Needs proof reading!!

The max rpm on a stock lude should be 7800.

I don't know the stock tyre / wheel size for the 4g so had a guess at it which will be why the 4g one is out.

I've got the 4g at 205/55/15 & the 5g at 205/50/16

The speed per gear wouldn't work if the numbers were wrong.
