More so the L series, how does the chassis take it? What would I expect to bend/break in a 13s 1/4.

keen to hear tales of twisted diff hangers or worse...

Are you kidding me… its an L series!!!

I have had my whole front end seam welded from when it was rallied & also have a cross brace as well. In it's current tune, mine is running mid 13's but have run a high 12 with a larger turbo & more boost etc.
Haven't had any probs with chassis flex, only mechanical dramas

I have a stock MY coupe that although it has never backed it up on the strip is definitely in low 13's territory.

Never had a single problem with the chassis. Actually nothing apart from rear axles and the clutch has had a rough time with the horsepower.

give me 6 weeks and I'll be able to tell you

Oh I should've mentioned I did twist up my diff hanger in the first week.

Welded two together and haven't looked back since...

Where the top chassis rail meets the front windscreen is a definite weak area - everything foward of the windscreen likes to flex away from the body! (the factory RX rallycars had some fairly seroius plating in this area).

Seam welding the front strut towers and lower & upper chassis rails is a good idea. Plating &/or triangulating the top rail back to the body is a better idea!

Now I find out AFTER I've had the engine bay painted....
Would've been perfect time to have it welded.

Thanks guys,

Have seamwelded most of the frontend, have added reinforcing plates around mention areas, triangulated peice between the top rail and the body done. Not sure if it my imagination but it feels heaps tighter (shake test, highly accurate...)

Was checking if there was anything else that should be taken care of when its a bare shell, havent touched the back yet, worth worring about?

I wouldnt bother with anything else, especially if its a street driven car that occassionally sees the strip - it should hold up fine as is.

talk to oversteer, he had one of the quicker L wagons around

hey Will, hope that guide was of some help i would've put the guide on to the site to download but couldnt work it out. pretty good read i think. i like the mods to the intake and the specs for the motor good read. anyway hope it helped...

cheers BEN

thanks for that, looks like my_sti is hosting it.
Interesting the odd bits for reinforcing ..A and B, but i guess it makes sense..
I wonder if for B, you need to remove the rain channel first (can't see how?) before applying the plate.......
