hi guys

just bought my e60 530d today - really impressive so far.

already got a few plans for it:

1. i am getting a remap - how easy is it to do an egr delete also? will it make any warning lights come on?

2. what are the standard size alloys? width and offset? i am looking to change to 18's or 19's and want them wider than currently

3. what decat options are available as cant find any? what gains do they give?

4. what is the best susepsnion to lower the car? i have seen some pro sport coilovers for £250 which is good price, also seen some eibach springs for £220....... the eibachs only lower by 30mm which is not enough. is it simplee enough to change the suspension? as in theres no air setting or anything that will be thrown out?

sorry to ask, but what is the main forum between this one and another i found called forum.bmw5.co.uk? is there a difference between the 2 forums?
