Thought it may be worthwhile to compile a list of online stores that people have found useful and good to deal with.
http://rhdjapan.com/ Great for model specific aftermarket parts and OEM parts.
http://www.sonicperformance.com.au/home.php Local company, have a great range of products. Trying to get a forum discount
http://www.nengun.com/ Also good for model specific parts. I think some have had issues with shipment times but i have not had a drama with them previously.
http://www.horsepowerinabox.com/ One of the better local sites. Morrie who runs it is an Adelaide boy and has always been great to deal with. Some of their prices for consumables and various parts are exceptional.
http://www.revolutionracegear.com.au....php?MMID=1487 Great site for those of us into racing.
http://www.pineappleracing.com/index.asp They have some excellent and unique products, such as the LIM, the idler pulley kit for those with no air pump, also have all your OEM parts, rebuild kits etc. US so shipping can hurt. They are prompt with email replies and shipping though.
http://www.banzai-racing.com/ Great things like block off kits, diff brace, oil pan brace, engine mounts.
http://www.rx7store.net/ Awesome site for RX7 specific stuff. From the states so shipping can hurt. Their replies to emails were poor and shipping was ridiculous. $80US dearer than racing beat. Have used these guys for their fuel rails, have been much better to deal with.
http://racingbeat.com/ Similar to rx7store, again from the states so shipping can hurt, but they have some great stuff. These guys were great. They replied promptly to my technical questions and their freight quote was very good. They also got the goods out in exceptional time.
http://www.atkinsrotary.com/ Some unique parts like the solid 2mm corner seals. They were fantastic to deal with, exceptionally prompt and good with emails. Parts were sent in excellent time.
http://www.perfectrun.com.au/ Never used them, but an alternative.
http://www.compfriction.com.au/ Probably one of the cheapest place for brake/clutch gear.
http://www.alamomotorsports.com/fjo/ For the FJO inj driver, best price for freight etc
Greenline Motorsports... http://www.greenline.jp/
http://rx7.com/index.html
http://www.fighters-garage.com/rx7.html
www.tirerack.com Fantastic price on wheels, freight much fairer than places like vivid racing. Communication can be poor, but if you email [email protected] you will get good service. Their price on semi slicks also puts local market to shame.
http://www.srmotorsports.com/sr9395rx.html Heaps of variety in parts, they are racers too, so i would guess products are well tested?

Will add more as people post.
