10% less weight for me would be 150kg so weight for sure. Brembos already stop me plenty well.

If i still my bucket of crap, I would have gone 10% more power, as it was already bordering at being in the high 1200kg range, so it's weight wasnt an issue.

25 hp at the wheels would have been good

less weight, because it will improve all the others... maybe by 10% each.

10% more grip - listen to any race car driver in any category (F1, V8, WRC, ARC) and they'll always want more grip.

That's because they have to work with fixed weight restrictions. They are not allowed to reduce weight even if there is weight to remove. Plus they already have the best competition tyres possible.

10% weight reduction for me. That's a good 130kg.

Grip applies to budget categories, Dutton, AHG Sprint, etc (perhaps not drifting).

Grip is just as important in drift despite appearances

If I owned a pig nose I'd want 10% better looks.
But in reality I'd go for weight reduction.

So, out of everybody that has said weight reduction over power, grip and braking who has actually done it before the above?

I'd bet that most WRX owners are driving 'round with more weight than they began with, but with more power, grip and brakes to throw it all around with.

10% weight reduction for SURE, but thats because my car is already making decent power.
