Y87 = performance package w/ 3.42s, Lower steering ratio and something else...

A4 = Automatic 4 spd

M5 = Manual 5 spd

[Camaro_SLP]

Y87 is a special package..comes with 3.42 gears and lsd...

A4 = Automatic 4-gear

M5 = Manual 5-gear

[Bliggida]

A4 and M5 are just slang abbreviations.

The actual RPO code for the 5-speed manual T-5 transmission is the "M49"

And the 4L60-E Automatic 4-speed transmission code is the "M30"

Only M30 equipped Y87 cars came with 3.42's.
M49 equipped Y87 cars still got the same 3.23's as non Y87 M49 cars.

Y87 = 14:1 steering ratio (instead of regular 16:1) with autocross designed power steering cooler, Zexel-Torsen Limited Slip Differential, 3.42's (for M30 cars), and low restriction dual outlet muffler.

Sorry, No. Power steering coolers were only available on V8 WS6 and 1LE cars.

To all the neebies - this kind of information is in the Tech Database.

BTW, the Y87 package was NOT available in 94.

[BigED]

Yes, its the Firebird version of the Camaro SS...

Yes, it's the Ram Air package for the TA.
WS6 is the actual RPO code and also became the name of the package.
LT1's were done by SLP.
LS1's were done by ASCD.
The Firehawk was the SLP package for the LS1.

WS6 came with:
17" wheels
badging
Ram Air Hood (functional)
Raised Air Box
Power steering cooler
Low restriction exhaust (read: cat-back)
"Specifically tuned suspension"

I thought the Firebird version of the Camaro SS was the Firehawk?

[Bliggida]

No, GM didn't actually make the "Firehawk", that was done by SLP.

GM only made the Trans-Am and Camaro SS.

Power steering cooler was not only available on the Trans-Am WS6...(goes without saying) also the SS Camaro.

Wasn't part of the performance steering on the Y87, that's my mistake. However I reccommend installing it none-the-less.

[pigglyroot]

SLP definately did the SS.

Y87 - signal given by us slow V6ers when we wanna say WhY 87 meaning why can I trap only 87mph

A4 - always 4...as in seems like it's always running on four cylinders

M5 - meaning we're dreaming about owning an BMW M5 on a topspeed run.
