When Are Traction Arms Needed?

[eXquiSit]

ok just changed the rear cradle on a s2 rwd auto stagea to the narrower s14 cradle

i have adjustable camber arms in

toe is -15mm on both sides, i need longer toe arms

i was told that when i got adjustable toe arms to also get traction arms

car is not overly low

question is, do i really need to get traction arms?

was going to run a street set up from this:

ie:

Recommended Road Settings
Front
Caster = 7 degrees positive (slightly more on the LHS to counter the drift to the gutter)
Camber = 1.25 to 1.5 degrees negative
Toe = Zero

Rear
Camber = 0.75 to 1.25 degrees negative
Toe = In 2 mm each side

traction arms are always needed otherwise your car will crash to the ground. HA. HA.

adjustable ones help with reducing bump steer when you lower the car, so you need them if you have noticed a bump steer problem and want to spend some time on an alignment hoist dialling it out.

or, you could just chuck them in, adjust them to % of stock length based on how much you shortened the camber arm by and feel like it improved things like most people do

ah so not a necessity?

it all seems like guess work when people install them!

What's 'not overly low' more specifically?

If you drop the car from standard heights to anything more decent it's probably lowered an inch or more, and you might want to change the traction arms too. eBay arms are <$100, you'll spend more than that in one proper alignment.

You can definitely run without, I did for years. Putting in adjustable traction arms did help with bump steer a little, however the main culprit turned out to be a busted shock on one side.

i suppose it isnt the worry about money, more so that i need it in a hurry and also that the alligner may not know what to do with it! lol

i may run the gauntlet of no traction arm first, adjustable toe and camber, and then see how the car feels

No fking way you would drive it with 15mm toe out per side. I presume you still have the standard eccentric bushes but no way can they get that much adjustment. You will scrub out your tyres in a few hundred km if you drive it in the current state.

yea im getting adjustable toe arms, just unsure of the need for traction arms, as per my first post

[iruvyouskyrine]

Sorry haha, was late and I obviously wasn't reading correctly.

I don't know how advantageous it would be running aftermarket traction arms in a street car. Personally I would but if you track it sometimes and are semi-serious about it, then it's probably worthwhile.
