: STS 2005 questions.

05-18-09, 08:22 PM
Ok I figure I just list what I have questions about in this one topic :) hope you guys can help me out.

I just bought a silver 205 sts northstar.

The light inside the headlight, not the low/high beam, what is that bulb size?

Also I am thinking about getting a stick or after market touch screen nav screen. what do I gain other the the screen by buying the stock, what do i need to get most of the options? what do i lost if i were to go to a aftermarket head touch screen head unit?

has anyone got 9.5" wide rwd rims under there car that are 22"?

The search function is your friend for all those questions.

Quickly: you can find the bulb size by searching Headlight in all forums. Note, you have to remove either the bumper or the fenderwells to replace the bulbs.

What do you mean getting a stick?

You cant do an aftermarket touch screen nav. You will lose your driver information center, and its crazy hard complicated to find an install bracket/wiring that works properly. I was going to put aftermarket nav in my CTS, but gave up and just upgraded to an STS with nav in it. You will literally spend a thousand dollars on the install alone on a Nav unit, not including the price of the unit.

Wheels, use search.

meant to say stock not stick.

i must be searching the wrong name for the lightbulb cause i keep getting fog light or head light.

Congradulations on your purchase.

Much of what you asked has been discussed in depth. I'd suggest you spend some time with the search feature to get all the info you'd ever want. I'll help a bit, with a few a swings...

I'd check the manual for the bulbs. Did you get one with the car? I've read that while its possible to change the bulbs without removing the bumper, it's not easy at all.

If you don't have factory Navigation, it's not worth trying to add it. The wiring is not there. So if your car doesn't have it and you want Nav, get a Garmin or equivilent.

If you change the Bose head-end, you lose the ability to change your memory settings.

A lot of members go with 20" wheels. 22's would be extreme. Anyone try it?

i read people doing 22" but i never hear anyone mention a width. and i see front parking light and turn signal, but what is that little bulb in the headlight called? if i can figure out the name i could find the bulb in the book hehe.

i believe i found it finally. someone called it a stock triangle headlight bulb. if that is true, then it is 194 bulb.

Hey - K STS! You're a couple 1/10's faster to 60, but I won't get stuck!

I think hes talking about his STS4 V8 vs my RWD V8. No clue why he put it here, haha

I thought it was funny the two of us wrote similar posts at about the same time, but he posted first. Not so funny I guess. Sorry for the confusion. :o

ugh i dont think cadillac wanted the head lights to be easy swaps for the bulbs. ugh. i need to take the bumper off? :(

Leave the bumper on, and go through the inner wheel wells. It is much easier that way and less of a pain in the ass...

#2 - YES. You can go 9.5 inch 22 inch wheels and tires. 255-30-22 tires are used on STS's. I would not get the 22es because your sidewall will be a rubber band. You will crack your wheels EXTREMELY easily. I have 245-40-20 inch wheels and tires. I have much more tire and meat for potholes and such.

How wide can you go on a 20 inch rim in the rear?? 10? 12?

05-21-09, 03:22 PM

Ok i just gonna sell the 22x9.5 i got and get 20x8.5 since I heard that is the correct size to run with and 245/35/20 tires.
