Is it an RS shell? I thought there was an option of a lightweight body. At first I thought it was just thinner panels but somebody told me that it was acid dipped. Don't know if its true but might be worth looking into.
Yes it is a Gp N rally car built from RS donor car (it is too much of a hassle to build one from a GSR model)
We have learnt a lot of things about the E7 so far and want to make a lot of fabrication changes when we rebuild it at the ends of the season... so the idea is that we dip it to get a nice bare metal shell to refabricate and save about 50 kg in the process.
In a Gp N rally car 50kg is an awful lot of weight to save...!!!!!!
would contact HARRY HOCKLEY not ADR OR EARS . you need some one who builds cars for works teams . personal i would not dip the shell because of the new adhesives used . save your money last i heard was it cost around £600 to have the shell acid dipped . there are loads of simple a free things to do first. what sort of a gap are you trying to make up or gain ????? seconds per km etc . why not just get better fuel and tryes !!!!!!!!
