Ignore the booster after t2. Instead, go wider and maintain your speed to get a wider line for t3. After t3, carry speed (not too much) and hit the wall on the edge of t3. this will line up your car for t4 apex and maintain about 120ish speed.

I could try it.

I've hit a 25.99 and I ignored the wall, might be interesting to see the speed with this technique

we will see

but you can drive out to the left to drive over more of the booster to get more speed to get a faster time maybe

The problem is to get the booster you need to have next to no speed (120 odd vs 140 skipping it) to hit it and it isn't fast

no i ment at the start of the race for the first booster
