Sigma Arms VS Corona Arms

[hugh]

Hey Guys,
I know there is a lot of talk on here about both these arms, but I havent heard anyone actually compare the two. I know Sigma Arms apparently give 5 degrees neg camber and corona give 3 degrees neg camber. Ive also read that you wouldn't really want to run more than about 3 degrees, so would that mean you would need camber tops to minimise some of the camber if you were running Sigma control arms? Which ones do you guys rate as better?

i hear corona ones are better, though there's a model of sigma with control arms that give less than the 5 degrees (3 degrees ish).

Here ya go, searching will find lot's of info as this stuff has been covered alot.

sigma arms+daily=defect central. front tyres get bald as on the inside really quickly. i forgot who it was but someone on the last big qld cruise got a major defect for this. -3 points for his license poor fellah

demerits for camber? WTF

bullshit


VT commodores have that on the rear lol!


i guess the track thing they hate too

Corona is better

Sigmas give massive track which can make the rear of the car pretty loose on higher speed turn ins (not good loose) also i found with camber tops maxxed out and sigmas you still had 3-4* camber which is a bit much on a daily. i was also using RCA's which alters the LCA angle which in turn reduces the track and camber gains slightly as the arm is not sitting dead flat which is effectively the longest the LCA can be.

Corona's give 2 - 2.5* depending on height therefore LCA angle. if you use RCA's your track and camber gain will be minimal but its still a gain

ideally you want an arm somewhere inbetween, from memory Corona's are 10mm longer and Sigma's 30mm. 15-20mm would be ideal but for this you need adjustable lower arms which are obviously more expensive than the above mentioned items you would find at a wreckers for $40ish

Coronas > Sigma's

defect wasnt for camber. it was cuz from looking at his tyres tehy were brand new but when the cop asked him to turn it to full lock the inside edge was completely bald. and that is considered a major defect up these ways
