I cut it out re-plated it and seam welded the whole subframe, strengthening all the key points, its now in Oli davies Pink cup car.

thanks for the offer robbie...but repairing it is the issue at the moment...i'm also wondering is the corrosion due to stress!

[Matt@CodeRedMotorsports]

Nah, more likely crappy design, also 20 odd years of water being thrown at it.:(

seems a bit odd that its on both sides...same place!! there must be more incidences of this in Old Blighty seeing that the roads there in the winter are practically seawater!they only started using pure salt here about 5 years ago!!
