Default New here!

Even though it is my username maybe I should add this

The car is 2006 grand prix gxp

Hi all. New to the whole FWD v8 5.3 ls4

I'm seeking info for stock tires for an aggressive/normal daily driving/mostly highway.
Also I would like to get opinions on tune-up the shbang

I just bought the car about 2 weeks ago and it needs tires and cylinder one coil (I wanted to look into the plugs and wire) and the rest or tune up. Waterpump also went out and could use some useful info on that as well.

Also with the hud I can't seem to figure out how to repair or replace it

Brands, sizes, goods, bads..........

Thank you to all that can assist a noob

These cars have been around since 2005, lots of useful info on this site. GXP has different size tires front and rear, if matching is important it will limit your search. Start by entering your car info in TireRack. This site has not much action so learn to use the search feature first. Good luck with your new ride.

Well still all searchable. Replies will be few and far between as the site is not very active now. If you want some info best be willing to hunt .Be active and keep posting on your progress. This site has a LS4 section, but it is not very active either.

http://www.grandprixforums.net/forum.php

Facebook I believe has something as well.
