I just got my 89 Rx7 FC.. i was wondering.. whats the offset for it? and also when i got my car my idle was jumping.. and it seemed to take longer to warm up.. and when i turn on the air conditioner the idle doesnt jump anymore... if you can help me id appreciate it thanks

if your idle is a pattern up down up down then your tps need adjusted, the backspacing is like +40mm or however you say it.
