The only draw back to trimming I would imagine would be the jagged edge left behind.

when we trim there is no jagged edge...

and also, we trim as far as we need to for adequate clearance... i believe these cars had 9 and 9.5" wheel that are mentioned...

and they dont have rubbing issues now...

we mark the line we want on the lip.....then tape it with painters tape for a guide, then put thick duct tape and masking tape on the outside of the car.... to prevent any accidents..

we then use a cutoff wheel and make a guide cut, then we cut through...

we then smooth it with a 90 degree hand held grinding disc with an abrasive pad.... we then prep the metal with cleaner and then rubbing alcohol, then spray it with high quality underbody coating.

2 hours of labor in total @100 per hour

keep in mind, we have a professional fender rolling tool, but we prefer this method on the evo.

cheers

are you saying thats high?

if you are, i think its a bargain, considering you avoid the risk of doing it yourself, and avoid the risk of creasing or paint cracking....

and, well, you can play the race simulators at our shop

I've spoken to Cal at Speedelement about this dilemma that i had and he explained to me that the risk of trimming the fender lip is that it loses some of its integrity. CBRD, do you notice this problem with cutting the fenders? Does the fender become weaker? On the other hand, if you roll your fenders, you will notice a slight bulge near the bumper mounts that are located on the fender. I admit i am a perfectionist and i can notice every conspicuous detail on my car. So after giving it some thought, here's what my conscious mind came up with. If i decided to trim the fender lip, i would trim it and reinforce the fender with two, maybe three layers of composite fiber (kevlar/carbon weave or carbon weave or structural fiberglass) with a medium hardness epoxy resin on the inside panel of the fender. That way i the section would have mild strength while maintaining flexibility. I noticed this is what Subaru did (BTW, my subaru is my dd) in my GC8. There is a ~4"X10" piece of hard material that is adhered to the inside of the quarter panel to give it strength. I can snap some pictures if you are interested.

Mike
