AHA! :rolleyes: You've given the plot away again, Sow :D

Julius, I think this is another one of those "gentle, gentle, slowly" thing hoping to get a free ride in the luggage haul to Brazil. :D :smile: :lol:

Sparksy, thanks for the pic. I think this is a small price to pay (i.e. if it just takes a small shaving off the bulkhead) for the added steering and less risk of the rear stepping out as per Julius's input. :)

Let"s say everyting else remain the same, you only change to softer dampening (means lower on both oil and spring rate alltogether).. this will make the car rolls more.. I think it can only react quicker and harder to drive if using softer oil but harder springs. Sure, driving style plays important role as well.

OK..Agreed on the driving style, that is definately a factor.

The softer dampening that you mention I understand but if the car is rolling more then the reaction is slower because it is rolling. If you are running hard dapening the car is not rolling as much therefore reacting quicker.

I think what you are saying is that the dampening reaction will be faster will the softer dampening which I agree but I am talking about the car reaction.... for eg..a chicane where the car has to change direction quickly, or also cornering. I want the car to be quicker reacting than it is at the moment

You can also lower your frontrollcenter to get a faster steeringinput. Try different settings and you'll be surprised:nod: :D

How is it now hitting the bulkhead? That is not the new part so how would it change anything? I installed the new saver and it did not change the clearence on mine.

Like I said, leave the red springs and put around 40WT Trinity grade oil.

Sow, I've been running 16/61 for the past 20 tanks without stripping or modding. I can't seem to figure out what i did wrong in the past but it seems to work fine now....:confused: :confused: :confused: Mebbe it's better meshed with a smaller 2nd gear pinion. 16/61 and 21/56 is my current combo. Oh yah, I've tried it on both blk and bronze pinions and they both work....Strange but true...:weird: :weird: :weird:

To the drivers steering input it's true, but how come less roll=more steering?

I once asked the same question and Julius did reply that the effect is not the same when putting thicker oil with more holes and using softer oil with less holes. They feel the same but they are actually not.

Onkel Sow, if you have to use 16T pinion, you could use 16/60 combo which gives 7.03 FDR. 16/61 combo gives 7.15 FDR. You will note that if you want to get the same rollout as using 16/61 when using 16/60, you need to use 1 mm smaller tires all around when you're on 16/60 to achieve the same kind of acceleration.;)

Making 61T larger would defeat the purpose I think since you'll have meshing problems with other 17T and 18T 1sy gear pinions.

From what you say about you needing to use softer springs and hard to get the power down, it sounds like the track you run on is pretty loose. Softer tires perhaps?
