You can just buy the brake cooling ducts, the grill "inserts" for the Redline, for the look and cooling benefits to your base 2.4 model.
The fender liner parts are more than likely not needed, for this conversion however. New liner runs around $48. times 2 here give or take.
After the removal of both old ones, then the re-install of new ones, seems a bit expensive and work involved for brake cooling.
How much brake cooling does it actually do here?
Small hole saw, Dremel tool... and your in business. Now for the connecting tubes you can save money by using parts from Home Depot, Lowes.
Downspout from the gutters to your house, the black fitment attachments square end/round end, and tubing, that black ribbed 6' drainage tubes works.
Even the dryer vent tubing, the shiny silver foil or the metal version could be used here. Couple of wire ties and your in business for less money.
You could spent well over $100. on the new fender liners OEM parts, plus tax & shipping/wait time. The Home Depot/Lowes option might cost less than $30.
I think Robo has photos of his conversion on this project? I have done this Home Depot routine, but on a different car, and not... for brake cooling.
I made a dual snorkel air cleaner, with forced ram air intakes for my Formula Firebird back in the day. Made a difference too!
IF... you need brake cooling? In stop and go city traffic, your brakes do heat up some, a given. No air flow through these vents to cool the brakes however.
Only at high speed would there be enough air to cool down your brakes, then again at hwy. speeds your not using your brakes enough to over heat them.
On a track day event, auto cross, time attack... yes you could over heat your brakes. You could cool them some, with these vents.
Better brake fluid Dot 5, pads, vented/slotted or crossed drilled rotors would be the option here, but the cost would be expensive to say the lest.
Your money, your car.. for the looks or for the need, it's all good.
* Emmett- Tomorrow I'm replacing the convertible top so I'm watching my car budget.
I'll be interested in your results for this. I am thinking about doing mine too.
In fact I have to make a few repairs to mine today. Couple of seams let go the other day.. on my first drop the top day cruise to
Summit Point Raceway the other day. New top is on my To-Do list. I have no shops near where I live to do this replacement. I have the $$$ for this now.
Finding a shop with a good reputation and previous history doing this is.. a whole different matter here in the DMV region however.
