If, so that's not a real comparison.
Ed has also mentioned he's using PSS, so it won't necessarily have the same effect on standard pistons.

Fact is after quite a bit of testing we simply can not get the 18 to go as fast on low traction asphalt with the standard ULP shock package compared to the 17!
Going by what Ed has said modifications are required to shorten the shock shafts by physically cutting them.
The whole idea of a new model is that it should be superior to the old one.
Now don"t get me wrong... I love this car... but with the 17 shocks and towers fitted.
I ALSO accept this appears to be only a problem on low-mid traction asphalt.
On a car this expensive we should not need to be modifying shock shafts or be faced with purchasing expensive option parts ( PSS ) to make them perform.
Having said that I will get the Dremel out and shorten the shafts and try again.

My point was shortening the gap WITHOUT shortening the actual shaft did not work

I've clarified my post. Most of the top guys are running 0.5 low and wide on FF and FR. So lower roll-centre and wider track than kit.
It seems to give more steering without making the car edgy (so more corner speed). Have a look at any setup from Olly Jefferies or Zak Finlay and they'll probably be this way.

Where may I find said setup sheets from the above drivers for Asphalt racing. They do not appear to be on the Xray site.
Main reason I ask is I would like to know if they r running front pins low and wide whilst running narrow front hex's or std.
thanks again..

Only changes I made were;
Narrow hexes all round
400 oil in shocks (still with PSS/8.5mm gap)
5K diff
Droop at 5.4 F, 4.4R
Worked very well for mod in medium grip asphalt, with a few bumps. But for lower traction, it lacks rear grip, so am going to be working on that this week (probably back to 3° rear toe, softer rear bar, and put the motor mount flex screw fully forward to start with)

What makes the 18 faster with 17 tower and shocks beside the main chassi, is 18 motor mount same as the 17 beside the extra holes plate thanks

Pardon my ignorance, but I see folks talking about narrow hexes on the car.
Where, exactly, is this setting?

It’s a method of narrowing the track width at the wheel.
