Low Springs?

[LittleRedSpirit]

People often use the falcon spring option. Personally a cut falcon spring will be too stiff for me and my traction loving ways.

 

For grip go softer, for skids go harder. I use cut standards in the rear of my car with the correct length shock absorbers and it gets top traction. I also have some pedders springs from a corona which Id estimate to be 6kg/mm to swap them with if I desire to slide.

 

My fronts are fine at 6kg for pretty much whatever I want to do.

 

As far as finding them goes, you would be best to experiment with cutting springs from other cars for a while, try hard, try softer, see what you like and then when you are more confident in knowing what you want get the custom setup ordered. Get decent shock absorbers too, and for gods sake make sure your spring are captive or you may die.

For comparison's sake, what would the standard KE70 springs be in terms of kg/mm?

Also Littleredspirit, i take it you run 6mm front/4mm rear? How is that for ride comfort?

I think standard springs would be around 2.5kg if I had to guess. Any suspension shop worth their salt should be able to rate springs with a device they have if you simply must know. I think 6/4 is too stiff in the rear for traction, I have cut standard units in the rear and they are probably just over 3. Maybe less.

Awesome so i can use AU springs then?

You can but I personally would not.

 

The theory behind it is as follows.

 

- Falcon a big heavy car = fairly stiff spring rates compared to a rolla for the same ride quality as standard. If a rolla is say 2.5kg, then the falcon might be 4kg for the same ride quality

 

- Falcon springs are far too long for a lowered corolla. You will go close to cutting them in half to get the required length of spring. This means you will go close to doubling the stiffness of the springs.

 

- Cutting them will not change the stiffness of the metal, but it will reduce the amount of coils there are to flex and give you travel.

 

- Therefore you will end up with very stiff springs which will actually seriously harm the handling of your car. Stiffer is not better. This is a common 'rice' misconception which is utter bs. The only reason you could possibly want stiff springs front and rear is to build a dedicated circuit drift car.

 

- If you do not put in short stroke shock absorbers when you cut your springs then your springs will possibly fall out of their hats when the car becomes unweighted. With springs as stiff as cut AU springs then you will need very good dampers to control them adequately.

 

If you are willing to tolerate this much bs just to get cheap lowered springs then go ahead. Its not much effort to save the 350 odd dollars to hit up GSL rallysport for some lowered kings and decent kyb dampers. He will probably help you select the right length of shock absorber for your needs too.

 

Friends don't let friends use cut AU springs.

 

All of this is my personal opinion from having tried a few different combinations and writing it off as a fail.

 

If anyone has some conflicting experience feel free to post up.

ive asked a question about this sorta topic in GSL forum waiting untill normal working days are back so i can get a reply might be worth a read

[Budowski]

still no reply i guess GSL are busy people ?
