Groff, you sound pretty set. remember that the 05 uses all the same suspension gear off the 415/ta04 etc etc. So you can still use the d blocks from the 415, but it will be as wide as if you put the D blocks on the 415 etc. So suspension wise, u can use the same theories and parts between cars, but you will get different results due to different chassis' etc. I need a second set of 415 blocks for my cars. Ive run out of setup options when i ran out of blocks!
