Review : Pedders suspension kit ser1-3 rx7s
I have just installed the first gen rx7 Pedders suspension kit into my ser3!!!
It's the one available at www.autostyleautomotives.com comprising of:
4 lowered & uprated springs
4 matched shocks
25mm front sway bar
Polyurethane bushes for everything except the upper links at the rear.
New dust boots & bump-stops for the front struts
Also I have ditched the rear sway bar, in keeping with most of the guys on the track, and also a custom wheel alignment (basically more castor and camber). I have elongated lower control arms to allow more camber adjustment too that I got separately.
So far I'm extremely impressed with the results!
My observations so far:
The ride is firmer but certainly not harsh. It still grips the road well when the surface is not perfectly smooth, unlike some hot suspension setups I've had in other cars where over a rougher surface grip is lost and you go nowhere or sideways!!!
Also the rear axle doesn't cause as much drama over bumps either, such as skipping sideways, despite the increased spring rates. Maybe cos there's no rear sway bar transferring bumps from one wheel to the other?
The body roll is reduced massively over stock, even with the rear bar gone. So its much, much nicer around a corners now...it's actually beginning to feel like a sports car should!
The car before was a bit of an understeerer, especially with my locked diff
until the go pedal was mashed but now it is far more neutral handling and I can enter a corner heaps faster than before without the same understeer. Corner exit speed has improved a fair bit, but not hugely, but I guess that's more a function of traction loss at the tyres at the rear..hehehe
My only complaint...lol...is that the front bar isnt adjustable but i dunno if thats really that much of an issue really..tho it would be nice
The kit definitely transforms the handling immensely and at a pretty good price too! I reckon the setup is a good one for a genuine street car that sees some track work. So I have to give the kit a big thumbs up for sure!!!

dudes i dunno how much it is for you guys lucky enough to have the USD's buying power....but considering that $1 US = $1.70 AUS (approx?) it would be very cheap 
....although i guess there is postage costs,...

I tried the pedders lowered springs. The front were OK but the back one came in too low and I got problems with 205 tyres. Could get no information on their specs but like the shocks they may be made by Monroe.
I priced the setup at about $Aus1200 fitted, say around $US710 at the current exchange rate.

I dunno really....just what the place i bought i from said...
Although I have heard it said that Mazda change the position of the links in the ser3 slightly so maybe this changes the height a bit???
Either way I wanted the rear of mine to sit slighty lower with a full tank of juice, so to achieve that i just didtched the spring cushions. Then i got that spiral wrap designed for putting around wiring loons and put in on the first coil at the top so there wasnt metal on metal contact....works fine

According to my reference " the mounting points for the lower rear trailing arms were lowered by 20mm to provide roll understeer to reduce the RX-7s tail-happy tendencies."
I wanted a bit of softness at the rear as many of the roads I travel on are uneven so tried for about 110 spring rate. Still do not know the Pedder specs.
